وَعَنْ أَبِي مَالِكٍ الْأَشْجَعِي عَنْ أَبِيهِ قَالَ: كَانَ الرجل إِذا أسلم علمه النَّبِي صلى اللَّهُ عَلَيْهِ وَسَلَّمَ الصَّلَاةَ ثُمَّ أَمَرَهُ أَنْ يَدْعُوَ بِهَؤُلَاءِ الْكَلِمَاتِ: «اللَّهُمَّ اغْفِرْ لِي وَارْحَمْنِي وَاهْدِنِي وَعَافِنِي وَارْزُقْنِي» . رَوَاهُ مُسلم

Abu Malik al-Ashja‘i told on his father’s authority that when a man accepted Islam the Prophet instructed him in the prayer, then commanded him to make supplication with these words, “O God, forgive me, show mercy to me, guide me, grant me health, and grant me provision.” Muslim transmitted it.
