Ahadith

Abu Zaid ibn Thabit ibn Dhahak relates that the Holy Prophet said: He who takes a false oath that if he is not telling the truth he might become a follower of a faith other than Islam is already as he describes himself. He who kills himself with an instrument will be tormented with that instrument on the Day of Judgment. A person cannot offer as a vow that which does not belong to him. Cursing a believer is equal to slaying him (Bokhari and Muslim). (Al-Ahzab 60)

Abu Hurairah relates that the Holy Prophet said: It does not behove a righteous Muslim that he should be given to cursing (Muslim). (Al-Ahzab 60)

Abu Darda‘ relates that the Holy Prophet said: Those who are given to cursing will neither be intercessors nor witnesses on the Day of Judgment (Muslim). (Al-Ma'idah 3, Bani Isra'il 36)

Samurah ibn Jundub relates that the Holy Prophet said: Do not curse anyone with the curse or wrath of Allah or with the Fire (Abu Daud and Tirmidhi). (Al-Ma'idah 3, Bani Isra'il 36)

Abu Darda‘ relates that the Holy Prophet said: When a person curses something the curse ascends to heaven and all the gates of heaven are closed against it. Then it descends to the earth and the gates of the earth are closed against it. Then it turns right and left and when it finds no exit it turns to the one who has been cursed and attaches itself to him if he should be deserving of it, but if not it returns to the one who uttered it (Abu Daud). (Al-Ma'idah 3, Bani Isra'il 36)

Imran ibn Husain relates: While the Holy Prophet was on a journey a woman of the Ansar riding a she-camel abused it and cursed it. The Holy Prophet heard this and said: Take off the load from the she-camel and turn it loose for it has been cursed (Muslim). (Al-Ma'idah 3, Bani Isra'il 36)

Abu Barazah Nadhlah ibn Ubaid Aslami relates: A girl on a she-camel which was also carrying a load suddenly encountered the Holy Prophet and the mountain pass became narrow for her people. She shouted at her she-camel and cursed it. The Holy Prophet said: The she-camel that has been cursed shall not accompany us (Muslim).

Ibn Mas‘ud relates that the Holy Prophet said: Abuse of a Muslim is sin and his murder is disbelief (Bokhari and Muslim).

Abu Dharr relates that he heard the Holy Prophet say: Let no one reproach his brother with sin or disbelief else if he should not be deserving of the reproach it could rebound upon the one who utters it (Bokhari).
