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.

I asked Anas bin Malik regarding Al-Qunut during the prayer. Anas replied, Yes (Al-Qunut was said by the Prophet (ﷺ) in the prayer). I said, Is it before Bowing or after Bowing? Anas replied, (It was said) before (Bowing). I said, So-and-so informed me that you told him that it was said after Bowing. Anas replied, He was mistaken, for Allah's Messenger (ﷺ) said Al-Qunut after Bowing for one month. The Prophet (ﷺ) had sent some people called Al-Qurra who were seventy in number, to some pagan people who had concluded a peace treaty with Allah's Messenger (ﷺ) . But those who had concluded the treaty with Allah's Messenger (ﷺ) violated the treaty (and martyred all the seventy men). So Allah's Apostle said Al-Qunut after Bowing (in the prayer) for one month, invoking evil upon them.
