Hadeeth Qudsi 7:

On the authority of Uqbah ibnAmir (may Allah be pleased with him), who said: I heard the messengerof Allah   say:

Your Lord delights at a shepherdwho, on the peak of a mountain crag, gives the call to prayer andprays. Then Allah (glorified and exalted be He) say: Look at thisservant of Mine, he gives the call to prayer and performs the prayers;he is in awe of Me. I have forgiven My servant [his sins] and haveadmitted him to Paradise.
