Assalamu'alaykum What is the autheticity of below hadeeth? Who was that man who fought with jinn 'Abd-Allah ibn Mas'ood (May Allah be pleased with him) said: "A man from among the Companions of Muhammad Sallallahu'alayhiwasallam met a man from among the jinn. They wrestled, and the human knocked down the jinn. The human said to him, 'You look small and skinny to me, and your forearms look like the front paws of a dog. Do all the jinn look like this, or only you?' He said, 'No, by Allah, among them I am strong, but let us wrestle again, and if you defeat me I will teach you something that will do you good.' The human said, 'Fine.' He said, 'Recite: 'Allah! None has the right to be worshipped but He, the Ever-living, the One Who sustains and protects all that exists…' [Quran Aayat al-Kursi - al-Baqarah 2:255 - interpretation of the meaning]. The human said, 'Fine.' He said, 'You will never recite this in your house but the Shaytan will come out of it like a donkey breaking wind, and he will never come back in until the next morning.'" (Reported by al-Darimi, 3247)." Assalamu'alaykum

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

This story is reported by At-Tabaraani and Ad-Daaraqutni and the scholars criticized its chain of narration because Ash-Sha’bi did not hear from Ibn Mas’ood .

As regards the Companion that is mentioned in the Hadeeth, it is ‘Umar Ibn Al-Khattaab as per the narration by At-Tabaraani .

Allaah Knows best.
