The Book of Prayer
Bulugh al-Maram 304
Narrated Anas bin Malik (RA):
The Prophet (ﷺ) recited Qunut (supplication in the prayer) for one month after (rising up from the) bowing (position), invoking curse on some Arab tribes. Afterwards, he gave it up. [Agreed upon].
وَعَنْ أَنَسِ بْنِ مَالِكٍ ‏- رضى الله عنه ‏- { أَنَّ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-قَنَتَ شَهْرًا بَعْدَ اَلرُّكُوعِ , يَدْعُو عَلَى أَحْيَاءٍ مِنْ أَحْيَاءِ اَلْعَرَبِ , ثُمَّ تَرَكَهُ } مُتَّفَقٌ عَلَيْهِ .‏ 1
