A man asked how he should beg his Lord
He wanted the actual words, and was given four.
قُلِ اللَّهُمَّ اغْفِرْ لِي وَارْحَمْنِي وَعَافِنِي وَارْزُقْنِي
Allāhumma-ghfir lī wa-rḥamnī wa ʿāfinī wa-rzuqnī.
“O Allah, forgive me, have mercy on me, keep me well, and provide for me.”
Forgiveness, mercy, health, provision. He was told these gather together his world and his hereafter.
The full narration
