Sunan Abi Dawud, Hadith 1693

Abd Allah bin `Amr said : (Sufyan said : The version of the narrator Sulaiman does not go back to The Prophet (SAWS). Fitr and al-Hasan reported from him ) : The Messenger of Allah (SAWS) said : One who compensates is not a man who unites relationship : but the man who unites relationship is the one who joins it when the relationship is cut off.

حَدَّثَنَا ابْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، عَنِ الأَعْمَشِ، وَالْحَسَنِ بْنِ عَمْرٍو، وَفِطْرٍ، عَنْ مُجَاهِدٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، - قَالَ سُفْيَانُ وَلَمْ يَرْفَعْهُ سُلَيْمَانُ إِلَى النَّبِيِّ صلى الله عليه وسلم وَرَفَعَهُ فِطْرٌ وَالْحَسَنُ - قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ لَيْسَ الْوَاصِلُ بِالْمُكَافِئِ وَلَكِنَّ الْوَاصِلَ هُوَ الَّذِي إِذَا قُطِعَتْ رَحِمُهُ وَصَلَهَا ‏" ‏ ‏.‏
