The question of whether the moral teachings of the Qur'an and the Sunnah extend to non-Muslims, or whether they are confined to the believers alone, is one that deserves careful attention. While certain rulings are indeed particular to Muslims—such as funeral rites, marriage, and dietary laws, which are clearly delineated in the legal tradition—the broader exhortations to charity, kindness, and benevolence encompass Muslims and non-Muslims alike. A Muslim is called to be respectful and well-mannered toward humanity as a whole, for the Qur'an and Sunnah contain abundant indications that our moral paradigm applies to the bulk of mankind, with exceptions reserved only for the worst offenders against justice.
Among the foremost of moral priorities is the good treatment of blood relations, especially one's parents, whether or not they embrace Islam. Allah says: "We have enjoined upon humankind to be good to his parents… If they strive to make you associate with Me that of which you have no knowledge, do not obey them but accompany them kindly in the world." This verse concerns the very case in which parents oppose Islam, yet the obligation of kind treatment remains, disobedience being restricted to sinful demands alone. Ibn Kathīr (d. 1373) observes that their non-violent opposition "does not prevent you from accompanying them kindly in the world, meaning, to treat them both in the best manner." The tradition names this bond ṣilat al-raḥim, "connecting the womb," and the womb carries great significance. The Prophet ﷺ related that Allah told the womb, "Are you not pleased that I keep good relations with those who are good to you and I will cut off whoever severs relations with you?" He ﷺ also said, "The womb derives its name from the Most Merciful. Whoever keeps its relations, Allah will keep his relations. Whoever severs its relations, Allah will sever his relations."
The Prophet ﷺ himself embodied this teaching, for many of his Qurayshī relatives opposed him, sometimes violently, while others believed. Allah says, "Say: I do not ask you anything for (this message), except for the affection of relatives." As al-Ṭabarī (d. 923) records, some of the early Muslims understood this to mean that he ﷺ sought no worldly payment, "except for you to show me affection in my relations with you and to uphold our family ties between us"—and this even while they persisted in idolatry. He ﷺ declared openly, "The relatives of my father are not my allies. Verily, only Allah and the righteous believers are my allies. Yet, they have the bonds of kinship and I will uphold their family ties." When ʿUmar ibn al-Khaṭṭāb (rḍa) gave a silk garment gifted to him by the Prophet ﷺ to his idolatrous half-brother in Mecca, al-Nawawī (d. 1277) concluded that this constitutes "evidence for the permissibility of maintaining relations with relatives who are unbelievers and being good to them, as well as giving gifts to the unbelievers"—even those residing in hostile lands.
A verse frequently misused against Islam is Allah's saying: "You will not find people who have faith in Allah and the Last Day showing affection to those who oppose Allah and His Messenger, even if they were their fathers or their sons or their brothers or their kindred." This is misread when the word wadd, meaning "affection" or warmth, is rendered as "love" in the sense of desiring good for others. Qatādah ibn Diʿāmah al-Sadūsī (d. 735) explains that "those who oppose Allah and His Messenger" here refers to "those who show enmity"—namely those of Quraysh who persecuted the believers until they fled to Medina. To show warmth to such active oppressors would only embolden them; yet the Prophet ﷺ held out hope for reconciliation and ultimately forgave them, many freely entering Islam.
After family, neighbors hold the next place of importance, and Islam urges good conduct toward them regardless of religion. Allah says: "Worship Allah and associate nothing with Him, and be good to parents, relatives… the near neighbor, the far neighbor, the companion at your side…" Some scholars understood the "near" and "far" neighbor to signify a difference in religion rather than distance—the near being the Muslim and the far being the non-Muslim. Al-Qurṭubī (d. 1273) affirmed this as the correct opinion, holding benevolence commanded toward the neighbor "whether to a Muslim or an unbeliever." Mujāhid ibn Jabr (d. 722) reported that ʿAbd Allāh ibn ʿAmr (rḍa) instructed that his Jewish neighbor be given a portion of a roasted sheep, citing the Prophet ﷺ: "Gabriel continued to instruct me in regards to neighbors that I thought he would make them my heirs." Al-Tirmidhī noted similar reports from ʿĀʾishah, Ibn ʿAbbās, Anas, Abū Hurayrah, ʿUqbah ibn ʿĀmir, and Abū Umāmah (rḍa). The sole exception is kindness that aids an oppressor, for al-Ghazālī (d. 1111) rightly said, "Kindness to the oppressor is evil to the oppressed"; charity may not come at the expense of justice.
The classical scholars codified these protections in law, dividing peaceful non-Muslims into three protected classes: the dhimmī who lives under Muslim authority and pays taxes, the muʿāhid who lives under a peace treaty, and the mustaʾmin who enters with granted safety—the sole exception being the enemy combatant (ḥarbī). The Prophet ﷺ warned severely, "He will not enter Paradise whose neighbor is not secure from his evil," and, "Whoever kills a person protected by a treaty (muʿāhid) will not smell the fragrance of Paradise. Verily, its fragrance can be found from a distance of forty years of travel." He ﷺ further said that he would be the prosecutor on the Day of Resurrection against whoever wrongs such a person. So numerous are these narrations that al-Mawwāq (d. 1492) noted they "have been unanimously reported." Formal state protection is not strictly required for a person's inviolability, for Ibn Taymīyah (d. 1328) stated the governing principle: "The default rule (aṣl) is that the blood of the human being (Ādamī) is inviolable except by right of justice." Ibn Qudāmah (d. 1223) concurred that expiation is due for one wrongly killed "as if he was a Muslim." When al-Mughīrah (rḍa) killed and robbed men before Islam and then converted, the Prophet ﷺ accepted his Islam but rejected the wealth, saying, "it is the wealth of treachery and we have no need for it"; al-ʿAẓīmābādī (d. 1911) drew from this that seizing an unbeliever's wealth deceptively in a state of safety is unlawful.
Some prophetic words appear to address only "Muslims" or "believers," yet scholars understood exclusive language often to carry inclusive meaning, since he ﷺ frequently spoke to Muslim audiences whose needs shaped his wording. Just as male grammatical forms include women—al-Khaṭṭābī (d. 998) noting that "if the address is conveyed in the male grammatical form, it is also addressed to women, except for specific topics"—so too may "brother" stand for neighbor or humanity. He ﷺ said, "None of you have faith until he loves for his brother what he loves for himself," while another version reads "loves for people," and another uses "neighbor." Ibn Ḥajar al-Haytamī (d. 1566) held that "brother" here is "used in a general sense." Likewise, when asked whose Islam is best, he ﷺ answered in one narration, "One from whose tongue and hand Muslims are safe," and in another, "people are safe." Al-Nawawī explained that varied answers "were given as appropriate according to the variety of circumstances and individuals."
On this basis, scholars explicitly extended protection to non-Muslims in matters such as backbiting. Concerning the verse, "Would one of you like to eat the flesh of his dead brother?", Ibn Ḥajar al-Haytamī held the correct opinion to be that "it is forbidden to backbite a dhimmī," his reputation, life, and property being inviolable. Zakarīyā al-Anṣārī (d. 1520), Ibn al-Humām (d. 1457)—who rebuked those who insulted the dhimmī in the marketplace—and Ibn ʿĀbidīn (d. 1836), who noted some scholars deemed wronging a dhimmī even worse, all affirmed this. Al-Buhūtī (d. 1051) ruled that cursing a dhimmī by name warrants discipline, and al-Ḥaṣkafī recorded that insulting one is a punishable sin. The protection extended even to commerce, for the Prophet ﷺ said, "A man may not undermine the transactions of his brother," which al-Jamal (d. 1790) applied to the dhimmī, muʿāhid, and mustaʾmin alike, excluding only the combatant and apostate. Moreover, the covenant included a positive right to welfare: "He is not a believer whose stomach is filled while the neighbor to his side goes hungry." Al-Ghazālī cited al-Ḥasan al-Baṣrī (d. 728), who saw no harm in feeding Jewish and Christian neighbors. When ʿUmar (rḍa) found an aged Jewish man begging to pay his tax, he exempted him and provided for him from the treasury, saying, "we have not been fair to him," for the Prophet ﷺ said, "Be merciful to those on the earth and the One in the heavens will have mercy upon you."
In sum, the Prophet ﷺ addressed diverse audiences, employing general and specific terms interchangeably; his use of "brother" or "Muslim" does not necessarily confine a ruling to Muslims alone. Protected non-Muslims are morally and legally equal to Muslims in many important respects, the genuine distinctions between them—in funeral rites, marriage, and dietary law—resting upon explicit evidence. The teachings of kindness were never restricted to the believers, as affirmed in the Sunnah, the practice of the Companions, and the writings of the scholars; and Islam safeguards the person, property, and reputation of the peaceful non-Muslim as it does that of the Muslim. Success comes from Allah, and Allah knows best.
