Musannaf Ibn Abi Shaybah

Hazrat Mutarrif bin Abdullah bin Shukhair says that I went to the land of Shaam and saw a man performing prayer, bowing and prostrating without any pause in between. I thought to myself that I should sit and find out who this elder is. So I sat down. When he completed his prayer, I said, "O servant of Allah! Did you end your prayer after an odd number of rak‘ahs or even?" He replied, "I am unconcerned with that." I asked, "Who has made you unconcerned?" He said, "The noble angels who record deeds. Because whenever I prostrate, Allah the Exalted raises me one rank and removes one sin from me." I said, "O servant of Allah! Who are you?" He replied, "I am Abu Dharr." I immediately exclaimed, "May Mutarrif’s mother lose him, he is teaching Abu Dharr the Sunnah!" When I arrived at the house of Hazrat Ka‘b, I was told that he had been asking about me. When I met him, I mentioned to him what Hazrat Abu Dharr had said. He replied, "He speaks the truth."
