Ibn Shihab said: I heard from Sa'id bin al-Musayyib, Humayd bin 'Abd al-Rahman bin 'Awf, 'Ubaydullah bin 'Abdullah bin 'Utbah bin Mas'ud, and Sulayman bin Yasar; all of them said: We heard Abu Hurayrah (may Allah be pleased with him) say that I heard 'Umar (may Allah be pleased with him) say: If a woman is divorced by her husband with one or two divorces, then he leaves her until her 'iddah is over, and she marries another husband, then that second husband dies or divorces her, and then her first husband marries her again, then he will have the right to the remaining one divorce.
Imam Malik (may Allah have mercy on him) said: According to us, there is no difference of opinion in this matter.
