the Messenger of Allah returned his daughter to Abul-'As bin Rabi' after two years, on the basis of the first marriage contract. (Using translation from Ibn Mājah 2009)
أَنَّ رَسُولَ اللهِ ﷺ رَدَّ ابْنَتَهُ زَيْنَبَ عَلَى أَبِي الْعَاصِزَوْجِهَا بِنِكَاحِهَا الْأَوَّلِ بَعْدَ سَنَتَيْنِ وَلَمْ يُحْدِثْ صَدَاقًا
