Sahih al-Bukhari
Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Chapter: The Ghazwa of Ar-Raji’, Ri’l, Dhakwan and Bi’r Ma’una and the narration about Khubaib and his companions
Narrated Anas bin Malik:
The Prophet (ﷺ) invoked evil upon those (people) who killed his companions at Bir Mauna for 30 days (in the morning prayer). He invoked evil upon (tribes of) Ril, Lihyan and Usaiya who disobeyed Allah and His Apostle. Allah revealed a Qur'anic Verse to His Prophet regarding those who had been killed, i.e. the Muslims killed at Bir Ma'una, and we recited the Verse till later it was cancelled. (The Verse was:) 'Inform our people that we have met our Lord, and He is pleased with us, and we are pleased with Him."
