Abu Huraira said that a man came to the Prophet and told him he had contracted to marry a woman of the Ansar, to which he replied, “Then look at her, for there is something in the eyes of the Ansar.”*
* Meaning that some of them have features which cause aversion.
Ibn Mas'ud reported God’s Messenger as saying, “A woman must not come in close contact with another and then describe her to her husband, for that is as if he were looking at her.”
