the sinfulness and criminal liability also vary according to the one who inflicts the harm.
Yet—astonishing as it is—many Muslims today wrong their neighbors by crowding them, spying on their private affairs, and the like. This ranks among the gravest of sins. The Prophet ﷺ declared, “By Allah, he does not believe! By Allah, he does not believe! By Allah, he does not believe!”—three times. They asked, “Who is that, O Messenger of Allah?” He replied, “The one whose neighbor is not safe from his abuses,” meaning his oppression and tyranny.
Allah’s words, “for something they have not earned” (33:58), imply that when a believer is harmed for what he himself has earned, there is no blame in that. In practical terms, if you harm a person in lawful retaliation for the harm he inflicted on you, there is no sin. Likewise, if someone is harmed in order to carry out one of Allah’s prescribed penalties, or to oblige him to discharge a right he refuses to fulfill, there is no blame. Indeed, Allah commanded concerning the two who commit an indecent act: “As for the two of you who commit it, punish them both” (Q 4:16); thus He ordered that they be harmed, adding, “If they repent and mend their ways, then leave them alone.” This was before execution was legislated for both the active and passive participants in sodomy: at first the sodomite was neither flogged nor killed, but merely chastised until he repented. Later, Allah commanded—through His Prophet ﷺ—that both parties be put to death, and the Companions unanimously agreed on this.
The compiler next cites the hadith of ʿAbdullāh ibn Masʿūd (may Allah be pleased with him): “Reviling a Muslim is wickedness, and fighting him is disbelief.” From this it is clear that wickedness is less serious than disbelief, for the Prophet labelled verbal abuse wickedness whereas he classified fighting as disbelief. Accordingly, when a Muslim reviles his brother he becomes a fāsiq (open sinner): his testimony is rejected, he is denied guardianship, he may not act as a guardian even for his own daughter, because he has become a fāsiq; nor may he lead the Muslims in prayer, and
