Musannaf Ibn Abi Shaybah 2940 — Those who disliked a man passing

Abd al-Rahman bin Yazid said: "Once a man started to pass in front of Abd al-Hamid bin Abd al-Rahman, the governor of Umar bin Abd al-Aziz, while he was praying. He pulled him so hard that his clothes were about to tear. When he had completed his prayer, he said: the Messenger of Allah (peace and blessings be upon him) said: 'If the one passing in front of a person praying knew how much sin there is in it, he would prefer that his thigh be broken rather than pass in front of the one praying.'"
