Sahih Muslim | Book 8 | Hadith Number 3314
Narrated by Abu Huraira (Allah be pleased with him)
Abu Huraira (Allah be pleased with him) reported: I was in the company of Allah's Messenger (way peace be upon him) when there came a man and informed him that he had contracted to marry a woman of the Ansar. Thereupon Allah's Messenger (may peace be upon him) said: Did you cast a glance at her? He said: No. He said: Go and cast a glance at her, for there is something in the eyes of the Ansar.
