What decision did the Prophet Muhammad (saw) make regarding Khansa' bint Khidam Al-Ansariya's marriage which she disliked?
 Narrated Khansa' bint Khidam Al-Ansariya:                     That her father gave her in marriage when she was a matron and she disliked that marriage. So she came and (complained) to the Prophets and he declared that marriage invalid. (See Hadith No. 69, Vol. 7)
