عَنْ عِمْرَانَ بْنِ حُصَيْنٍ رَضِيَ اَللَّهُ عَنْهُمَا;
«أَنَّهُ سُئِلَ عَنْ اَلرَّجُلِ يُطَلِّقُ، ثُمَّ يُرَاجِعُ، وَلَا يُشْهِدُ? فَقَالَ: أَشْهِدْ عَلَى طَلَاقِهَا، وَعَلَى رَجْعَتِهَا»
He was asked about a man who divorces his wife, then takes her back without taking witnesses (on either). So he replied, “Get witnesses on her divorce, and on her return.”.
