Anas reported that Allah's Apostle (ﷺ) did not enter the house of any woman except that of his wives and that of Umm Sulaim. He used to visit her. It was said to him why it was so, whereupon he said
I feel great compassion for her. Her brother was killed while he was with me.
Anas reported that Allah's Apostle (ﷺ) said
I entered Paradise and heard the noise of steps. I said: Who is it? They said: She is Ghumaisa, daughter of Milhan, the mother of Anas b. Malik.
Jabir b. 'Abdullah reported that Allah's Messenger (ﷺ) said
I was shown Paradise and I saw the wife of Abu Talha (i.e. Umm Sulaim) and I heard the noise of steps before me and, lo, it was that of Bilal.
