He said, "My Lord, indeed my bones have weakened, and my head has filled1 with white, and never have I been in my supplication to You, my Lord, unhappy [i.e., disappointed].
Translation: Saheeh International (English)
1 Literally, "ignited." The spread of white hair throughout the head is likened to that of fire in the bush.
He said: “My Lord, indeed my bones have become weak, the white hairs on my head have increased, and I was not unsuccessful in my supplicating You. In fact, every time I supplicated You, You accepted.
