عَنْ مُسْلِمِ بْنِ أَبِي بَكْرَةَ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ يَقُولُ فِي دُبُرِ كُلِّ صَلَاةٍ: ((اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْكُفْرِ وَالْفَقْرِ وَعَذَابِ الْقَبْرِ))
It is narrated from Sayyiduna Abu Bakrah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) used to recite this supplication after every prayer: "O Allah! I seek refuge with You from disbelief, poverty, and the torment of the grave." (O Allah! I seek Your protection from disbelief, poverty, and the punishment of the grave.)
