Prayer he often recited
Nahj al-Balāgha|Volume 1|Book 1|Chapter 215
اللَّهُمْ إِنَّا نَعُوذُ بِكَ أَنْ نَذْهَبَ عَنْ قَوْلِكَ، أَوْ نُفْتَتَنَ عَنْ دِينِكَ، أَوْ تَتَابَعَ بِنَا أَهْوَاؤُنَا دُونَ الْهُدَى الَّذِي جَاءَ مِنْ عِنْدِكَ!
O my Allāh! We seek Thy protection from turning away from Thy command or revolting against Thy religion, or being led away by our desires instead of by guidance that comes from Thee.
