(31) Chapter: To vow for something not possessed, and for something sinful
باب النَّذْرِ فِيمَا لاَ يَمْلِكُ وَفِي مَعْصِيَةٍ
Narrated Ibn `Abbas:
The Prophet (ﷺ) saw a man performing Tawaf around the Ka`ba, tied with a rope or something else (while another person was holding him). The Prophet (ﷺ) cut that rope off.
