عَنْ سَعْدِ بْنِ أَبِي وَقَّاصٍ قَالَ: جَاءَ أَعْرَابِيٌّ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: عَلِّمْنِي كَلَامًا أَقُولُهُ قَالَ: «قُلْ لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ اللَّهُ أَكْبَرُ كَبِيرًا وَالْحَمْدُ لِلَّهِ كَثِيرًا وَسُبْحَانَ اللَّهِ رَبِّ الْعَالَمِينَ لَا حَوْلَ وَلَا قُوَّةَ إِلَى بِاللَّهِ الْعَزِيزِ الْحَكِيمِ» . فَقَالَ فَهَؤُلَاءِ لِرَبِّي فَمَا لِي؟ فَقَالَ: «قُلِ اللَّهُمَّ اغْفِرْ لِي وَارْحَمْنِي وَاهْدِنِي وَارْزُقْنِي وَعَافِنِي» . شَكَّ الرَّاوِي فِي «عَافِنِي» . رَوَاهُ مُسلم

Sa‘d b. Abu Waqqas said that a nomadic Arab come to God's messenger and asked him to teach him some words to say. He told him to say, “There is no god but God alone who has no partner; God is very great; Abundant praise is due to God; Glory be to God, the Lord of the universe; There is no might and no power except in God, the Mighty, the Wise.” On his remarking that these were for his Lord but he wanted to know what he should say for himself, he told him to say, “O God, forgive me, show mercy to me, guide me, provide for me, and grant me security.” The transmitter was doubtful about “grant me security.” Muslim transmitted it.
