Musnad Abu Ya'la al-Mawsili 155:346

Abu Ma'mar Isma'il ibn Ibrahim narrated to us, Ali ibn Hashim narrated to us, from Yazid ibn Kaysan, from Abu Hazim, from Abu Hurayrah: That a man married a woman from the Ansar. The Messenger of Allah (peace and blessings of Allah be upon him) said to him, "Did you not look at her? For there is something in the eyes of the Ansar." He said, "I have looked at her."
