Jubair bin Nufair reported: I went along with Shurahbil bin al-Simt to a village which was situated at a distance of seventeen or eighteen miles, and he said only two rak'ahs of prayer. I said to him (about it) and he said: I saw 'Umar observing two rak'ahs at Dhu'l-Hulaifa and I (too) said to him (about it) and he said: I am doing the same as I saw the Messenger of Allah (ﷺ) doing. (This hadith has been transmitted by Shu'bah with the same chain of narrators and it is narrated from Simt, and the name of Shurahbil has not been mentioned, and he said that he had gone to a place called Dumin, situated at a distance of eighteen miles from Hims.)

It has been narrated on the authority of Salman who said: I heard the Messenger of Allah (ﷺ) say: Keeping watch for a day and a night is better (in point of reward) than fasting for a whole month and standing in prayer every night. If a person dies (while, performing this duty), his (meritorious) activity will continue and he will go on receiving his reward for it perpetually and will be saved from the torture of the grave.

This tradition has been handed down on the authority of Salman al-Khair through another chain of transmitters.
