(117) باب ذِكْرِ النَّهْىِ عَنِ الْمَشْىِ، فِي نَعْلٍ وَاحِدَةٍ
It was narrated that Abu Razin said:
"I saw Abu Hurairah clap his hand to his forehead and say: 'O people of Al-'Iraq, you claim that I tell lies about the Messenger of Allah [SAW]. I bear witness that I heard the Messenger of Allah [SAW] say: If the strap of the sandal of one of you breaks, let him not walk in the other until he fixes it.'"
