" O Allah, grant me pardon, have mercy upon me, protect me, provide me sustenance," and he collected his fingers together except his thumb and said: It is in these words (that there is supplication) which sums up for you (the good) of this world and that of the Hereafter.
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَخْبَرَنَا أَبُو مَالِكٍ، عَنْ أَبِيهِ، أَنَّهُ سَمِعَ النَّبِيَّ صلى الله عليه وسلم وَأَتَاهُ رَجُلٌ فَقَالَ يَا رَسُولَ اللَّهِ كَيْفَ أَقُولُ حِينَ أَسْأَلُ رَبِّي قَالَ ‏
"‏ قُلِ اللَّهُمَّ اغْفِرْ لِي وَارْحَمْنِي وَعَافِنِي وَارْزُقْنِي ‏"‏ ‏.‏ وَيَجْمَعُ أَصَابِعَهُ إِلاَّ الإِبْهَامَ ‏"‏ فَإِنَّ هَؤُلاَءِ تَجْمَعُ لَكَ دُنْيَاكَ وَآخِرَتَكَ ‏"‏ ‏.‏
