Mishkat al-Masabih — Hadith #48149

On the authority of Ubayy bin Ka’b, he said: I said: O Messenger of God, I pray for you often, so how many of my prayers should I devote to you? He said: “Whatever you want.” I said: A quarter? He said: “Whatever you want, if you add more, it is better for you.” I said: Half? He said: “Whatever you want, and if you increase, it is better for you.” I said: So two-thirds? He said: “What?” Whatever you wish, if you add more, it is better for you.” I said: Should I make all my prayers for you? He said: “If your worry is enough and your sin is forgiven for you.” Narrated by Al-Tirmidhi
