عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَنَتَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ شَهْرًا بَعْدَ الرُّكُوعِ يَدْعُو عَلَى رِعْلٍ وَذَكْوَانَ، وَقَالَ: ((عُصَيَّةُ عَصَتِ اللَّهَ وَرَسُولَهُ))
Sayyiduna Anas bin Malik (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) recited the Qunoot supplication for a month after bowing (ruku’), in which he invoked curses upon the tribes of Ri’l and Dhakwan. Also, the Prophet (peace and blessings be upon him) said: The tribe of ‘Usayyah has disobeyed Allah and His Messenger.
