Musnad Abi Ya'la 4507 — groups of Arabs came to the Messenger of Allah

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that groups of Arabs came to the Messenger of Allah (peace and blessings be upon him) in such large numbers that they forced him (peace and blessings be upon him) (because of the crowd) to take refuge towards the house of Sayyidah Aishah (may Allah be pleased with her). He (peace and blessings be upon him) said (in displeasure): 'Allahumma il'anhum' (O Allah, curse them). Then Sayyidah Aishah (may Allah be pleased with her) said: "O Messenger of Allah (peace and blessings be upon him), these people are destroyed (by your supplication)." He (peace and blessings be upon him) said: "Not at all, O daughter of al-Siddiq! By Allah, I have made an agreement with my Lord which will not be broken. I said: 'Allahumma inni basharun adiqu bima yadiqu bihi al-basharu wa a'jalu bima ya'jalu bihi al-basharu, fa-ayyuma imri'in badarat minni badiratun faj'alha lahu kaffarah' (O Allah, I am a human being; I become weary just as humans become weary, and (under human impulses) I am quick (to anger) just as humans are. So whoever has a harsh word escape from my mouth against him, make it an expiation (of sins) for him)."
