Sunan an-Nasa'i 4182
It was narrted from a man from Al Ash-Sharid, who was called 'Amr, that his father said:
"Among the delegation of Thaqif there was a man who suffered from leprosy. The Prophet sent word to him saying: 'Go back, for I have accepted your pledge."'
أَخْبَرَنَا زِيَادُ بْنُ أَيُّوبَ، قَالَ حَدَّثَنَا هُشَيْمٌ، عَنْ يَعْلَى بْنِ عَطَاءٍ، عَنْ رَجُلٍ، مِنْ آلِ الشَّرِيدِ يُقَالُ لَهُ عَمْرٌو عَنْ أَبِيهِ قَالَ كَانَ فِي وَفْدِ ثَقِيفٍ رَجُلٌ مَجْذُومٌ فَأَرْسَلَ إِلَيْهِ النَّبِيُّ صلى الله عليه وسلم ‏
"‏ ارْجِعْ فَقَدْ بَايَعْتُكَ ‏"‏ ‏.‏
