Sahih Muslim: Hadith 1489

I came to the Messenger of Allah (ﷺ) and the rest of the hadith is the same as narrated (above) except this that a man said: Where is Malik b. Dukhshun or Dukhaishin, and also made this addition that Mahmud said: I narrated this ver hadith to many people and among them was Abu Ayyub al-Ansari who said: I cannot think that the Messenger of Allah (ﷺ) could have said so as you say. He (the narrator) said: I took an oath that if I ever go to 'Itban. I would ask him about it. So I went to him and found him to be a very aged man, having lost his eyesight, but he was the Imam of the people. I sat by his side and asked about this hadith and he narrated it In the same way as he had narrated it for the first time. Then so many other obligatory acts and commands were revealed which we see having been completed. So he who wants that he should not be deceived would not be deceived.
