It is narrated from Yusuf bin Mihran that he said: We were with Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both), and he said: If it would please you to see who among the Companions of Muhammad (peace and blessings be upon him) made no change or alteration (in his way), then look at Abdullah bin Umar (may Allah be pleased with them both), for every one of us has changed somewhat (according to circumstances), but he remained as he was.
