Mishkat al-Masabih 4581
‘Amr b. ash-Sharid told on his father’s authority that there was a man with tubercular leprosy in the deputation of Thaqif and the Prophet sent to him a message:
"We have taken your oath of allegiance, so go home." 

Muslim transmitted it.
وَعَنْ عَمْرِو بْنِ الشَّرِيدِ عَنْ أَبِيهِ قَالَ: كَانَ فِي وَفْدِ ثَقِيفٍ رَجُلٌ مَجْذُومٌ فَأَرْسَلَ إِلَيْهِ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّا قد بايعناك فَارْجِع» . رَوَاهُ مُسلم
