Invocations

Bukhari :: Book 8 :: Volume 75 :: Hadith 317

Narrated Anas:

that the Prophet said, "For every prophet there is an invocation that surely will be responded by Allah," (or said), "For every prophet there was an invocation with which he appealed to Allah, and his invocation was accepted (in his lifetime), but I kept my (this special) invocation to intercede for my followers on the Day of Resurrection."
