Chapter 37: Chapters on the description of the Day of Judgement, Ar-Riqaq, and Al-Wara'
An-Nadr bin Anas bin Malik narrated from his father who said: "I asked the Prophet (s. a. w) to intercede for me on the Day of Judgement. He said: 'I am the one to do so.'" [He said: ] "I said: 'O Messenger of Allah! Then where shall I seek you?' He said: 'Seek me, the first time you should seek me is on the Sirat.'" [He said: ] "I said: 'If I do not meet you upon the Sirat?' He said: 'Then seek me at the Mizan.' I said: 'And if I do not meet you at the Mizan?' He said: 'Then seek me at the Hawd, for indeed I will not me missed at these three locations.'"
