Yazid bin Khumayr (may Allah have mercy on him) narrates that:
I asked Sayyiduna Abdullah bin Busr (may Allah be pleased with him): "How is our condition compared with the condition of those who passed before us?" He said: "Subhan Allah (Glory be to Allah)! By Allah, if they were raised again from their graves, they would not recognize you (because of your changed ways), except that they might find you standing in prayer."
No one narrated this hadith from Sayyiduna Abdullah bin Busr (may Allah be pleased with him) except Yazid bin Khumayr (may Allah have mercy on him), and Safwan bin Amr (may Allah have mercy on him) is alone in narrating it.
