What was the call of Allah's Apostle (saw) according to the hadith given by Abu Huraira?
 Narrated Abu Huraira:                     Allah's Apostle (p.b.u.h) said, "Our Lord, the Blessed, the Superior, comes every night down on the nearest Heaven to us when the last third of the night remains, saying: "Is there anyone to invoke Me, so that I may respond to invocation? Is there anyone to ask Me, so that I may grant him his request? Is there anyone seeking My forgiveness, so that I may forgive him?"
