Sahih al-Bukhari 4858

It is related from al-Hasan that the sister of Ma'qil ibn Yasar was married to a man who divorced her and remained away from her until her 'idda ended. Then he proposed to her and Ma'qil was angry out of pride and said, "He kept away from her when he could keep her and now he proposes to her again?" He came between him and her and so Allah revealed, "When you divorce women and they reach the end of their waiting-period, do not prevent them from marrying their first husbands ..." (2:232) The Messenger of Allah, may Allah bless him and grant him peace, summoned him and recited it to him and so he set aside his anger and obeyed the command of Allah.
