While the Prophet ﷺ was performing Tawaf of the Kaʿba, he passed by a person who had tied his hands to another person with a rope or string or something like that. The Prophet ﷺ cut it with his own hands and said, "Lead him by the hand."  

أَنَّ النَّبِيَّ ﷺ مَرَّ وَهُوَ يَطُوفُ بِالْكَعْبَةِ بِإِنْسَانٍ رَبَطَ يَدَهُ إِلَى إِنْسَانٍ بِسَيْرٍ أَوْ بِخَيْطٍ أَوْ بِشَىْءٍ غَيْرِ ذَلِكَ فَقَطَعَهُ النَّبِيُّ ﷺ بِيَدِهِ ثُمَّ قَالَ قُدْهُ بِيَدِهِ
