Sunan Ibn Majah
It was narrated that Musa bin Talhah said: We were with Mu'awiyah and he said: "I heard the Messenger of Allah (ﷺ) say: 'Talhah is one of those who fulfilled their covenant.'"
حَدَّثَنَا أَحْمَدُ بْنُ سِنَانٍ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَنْبَأَنَا إِسْحَاقُ، عَنْ مُوسَى بْنِ طَلْحَةَ، قَالَ كُنَّا عِنْدَ مُعَاوِيَةَ فَقَالَ أَشْهَدُ لَسَمِعْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ " طَلْحَةُ مِمَّنْ قَضَى نَحْبَهُ " .
