Sahih al-Bukhari 3777

Hadith text

Narrated `Aisha:The day of Bu'ath (i.e. Day of fighting between the two tribes of the Ansar, the Aus and Khazraj) was brought about by Allah for the good of His Apostle so that when Allah's Messenger (ﷺ) reached (Medina), the tribes of Medina had already divided and their chiefs had been killed and wounded. So Allah had brought about the battle for the good of H is Apostle in order that they (i.e. the Ansar) might embrace Islam

Ayesha bataati hain: Bu'ath ka din (yaani Ansaar ke do qabilon, Aus aur Khazraj, ke beech jung ka din) Allah ne apne Rasool ki bhalaee ke liye laaya, taake jab Allah ke Rasool (Madina) pahunche, Madina ke qabile pahle se hi baante hue the aur unke sardaar mare ya zakhmi ho chuke the. Isliye Allah ne apne Rasool ki bhalaee ke liye us jung ko laaya taake woh (yaani Ansaar) Islam qubool kar saken.
