[Machine] The Messenger of Allah ﷺ used to spend thirty nights making supplications against the living of the Banu Sulaym, R'il, Dhakwan, and 'Usayyah, who had disobeyed Allah and His Messenger.
«إِنَّمَا قَنَتَ رَسُولُ اللهِ ﷺ ثَلَاثِينَ لَيْلَةً يَدْعُو عَلَى أَحْيَاءَ مِنْ بَنِي سُلَيْمٍ وَرِعْلٍ وَذَكْوَانَ وَعُصَيَّةَ عَصَوُا اللهَ وَرَسُولَهُ»
The Prophet ﷺ recited Qunut for one month (in the Fajr prayer) asking Allah to punish the tribes of Ral and Dhakwan. (Using translation from Bukhārī 1003)
قَنَتَ رَسُولُ اللهِ ﷺ شَهْرًا يَدْعُو عَلَى رِعْلٍ وَذَكْوَانَ وَبَنِي فُلَانٍ وَعُصَيَّةَ عَصَوْا اللهَ وَرَسُولَهُ قَالَ مَرْوَانُ يَعْنِي فَقُلْتُ لِأَنَسٍ قَنَتَ عُمَرُ؟ قَالَ عُمَرُ لَا
"The Messenger of Allah ﷺ prayed (saying the) Qunut after bowing for a month, supplicating against Ri'l, Dhakwan and 'Usayyah who had disobeyed Allah and His Messenger." (Sahih). (Using translation from Nasāʾī 1070)
قَنَتَ رَسُولُ اللهِ ﷺ شَهْرًا يَدْعُو عَلَى رِعْلٍ وَذَكْوَانَ وَبَنِي لِحْيَانَ وَعُصَيَّةَ عَصَوْا اللهَ وَرَسُولَهُ
