Sahl bin Saad reported the Messenger of Allah ﷺ as saying - in the tradition of spouses who invoked curses to each other “Look if she bears a child which has very black eyes, large buttocks, I cannot but imagine that he (i. e., ‘Uwaimir) has spoken the truth. But, if she bears a reddish child like the lizard with red spots (waharah), I cannot imagine that ‘Uwaimir has lied against her. She gave birth to a child (like that described the Prophet ﷺ ) in a detestable manner.
