Sahih al-Bukhari Book 61, Hadith 120
The Prophet (ﷺ) noticed the absence of Thabit bin Qais. A man said, "O Allah's Messenger (ﷺ)! I shall bring you
his news." So he went to him and saw him sitting in his house drooping his head (sadly). He asked
Thabit, "What's the matter?" Thabit replied, "An evil situation: A man used to raise his voice over the
voice of the Prophet (ﷺ) and so all his good deeds have been annulled and he is from the people of Hell."
The man went back and told the Prophet (ﷺ) that Thabit had said so-and-so. (The sub-narrator, Musa bin
Anas said, "The man went to Thabit again with glad tidings)." The Prophet (ﷺ) said to him, "Go and say
to Thabit: 'You are not from the people of Fire, but from the people of Paradise."
We complained to Allah's Messenger (ﷺ) (of the persecution inflicted on us by the infidels) while he was sitting in the shade of the Ka`ba, leaning over his Burd (i.e. covering sheet). We said to him, "Would you seek help for us? Would you pray to Allah for us?" He said, "Among the nations before you a (believing) man would be put in a ditch that was dug for him, and a saw would be put over his head and he would be cut into two pieces; yet that (torture) would not make him give up his religion. His body would be combed with iron combs that would remove his flesh from the bones and nerves, yet that would not make him abandon his religion. By Allah, this religion (i.e. Islam) will prevail till a traveler from Sana (in Yemen) to Hadrarmaut will fear none but Allah, or a wolf as regards his sheep, but you (people) are hasty.
A man recited Surat-al-Kahf (in his prayer) and in the house there was a (riding) animal which got frightened and started jumping. The man finished his prayer with Taslim, but behold! A mist or a cloud hovered over him. He informed the Prophet (ﷺ) of that and the Prophet (ﷺ) said, "O so-and-so! Recite, for this (mist or cloud) was a sign of peace descending for the recitation of Qur'an."
