Chapter 47: The Book Of Faith and its Signs
Abu Sa' eed Al-Khudri said: "The Messenger of Allah [SAW] said: 'While I was sleeping, I saw the people being shown to me, and they were wearing shirts. Some reached the breast and some reached lower than that. And 'Umar bin Al-Khattab was shown to me, and he was wearing a shirt that he was dragging;' They said: 'How do you interpret that, O Messenger of Allah?' He said: 'The religion.'"
