And when My servant
question thee concerning Me, then surely I am nigh. I answer the prayer
of the suppliant when he crieth unto Me. So let them bear My call and
let them trust in Me, in order that they may be led aright.
Narrated By An-Nu'man ibn Bashir : The Prophet (may
peace be upon him) said: Supplication (du'a') is itself the worship. (He then
recited:) "And your Lord said: Call on Me, I will answer you" (xI.60).
Abu Huraira reported Allah's Messenger (may peace be
upon him) as saying: The supplication of one of you is granted if he does
not grow impatient and say, I supplicated my Lord but it was not granted.
