While he was sitting with Abdullah bin Umar, Hajjaj bin Ayman came in and did not complete his ruku or his sujud properly, so Ibn Umar said to him, "Do it again."When the man had turned away, Ibn Umar asked me, "Who is this?"I said, "Hajjaj bin Ayman bin Umm Ayman."Ibn Umar said, "Had the Messenger of Allah ﷺ seen this man, he would have loved him." Then he spoke of the Prophet's love for him and for the children Umm Ayman bore.The narrator said: some of my companions also related this to me from Sulayman. She was the foster mother who nursed the Prophet ﷺ.
