سنن أبي داود

Narrated Abdullah ibn Umar:

Ibn Jurayj said: Ata' told me that he saw Ibn Umar pray after the Friday prayer. He moved a little from the place where he offered the Friday prayer. Then he would pray two rak'ahs. He then walked far away from that place and would offer four rak'ahs. I asked Ata': How many times did you see Ibn Umar do that? He replied: Many times. AbuDawud said: This has been narrated by AbdulMalik ibn AbuSulayman, but did not narrate it completely.
