Ibn ‘Abbas said that God’s Messenger stood in humble supplication daily for a month at the noon, afternoon; sunset, evening and morning prayer when he said, “God listens to him who praises Him” in the last <i>rak'a</i>, invoking a curse on some clans of the B. Sulaim, Ri‘l, Dhakwan and ‘Usayya, and those standing behind him said Amen. Abu Dawud transmitted it.

عَنِ ابْنِ عَبَّاسٍ قَالَ: قَنَتَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ شَهْرًا مُتَتَابِعًا فِي الظّهْر وَالْعصر وَالْمغْرب وَالْعشَاء وَصَلَاة الصُّبْح إِذا قَالَ: «سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ» مِنَ الرَّكْعَةِ الْآخِرَة يَدْعُو عَلَى أَحْيَاءٍ مَنْ بَنِي سُلَيْمٍ: عَلَى رِعْلٍ وَذَكْوَانَ وَعُصَيَّةَ وَيُؤَمِّنُ مَنْ خَلْفَهُ. رَوَاهُ أَبُو دَاوُد
