I bear witness to the fact that both Abu Huraira and Abu Sa'id Khudri were present when Allah's Messenger may peace be upon him) said: The people do not sit but they are surrounded by angels and covered by Mercy, and there descends upon them tranquillity as they remember Allah, and Allah makes a mention of them to those who are near Him. This hadith has been narrated on the authority of Shu'ba with the same chain of transmitters.
What makes you sit here? They said: We are sitting here in order to remember Allah. He said: I adjure you by Allah (to tell me whether you are sitting here for this very purpose)? They said: By Allah, we are sitting here for this very purpose. Thereupon, he said: I have not demanded you to take an oath, because of any allegation against you and none of my rank in the eye of Allah's Messenger (ﷺ) is the narrator of so few ahadith as I am. The fact is that Allah's Messenger (ﷺ) went out to the circle of his Companions and said: What makes you sit? They said: We are sitting here in order to remember Allah and to praise Him for He guided us to the path of Islam and He conferred favours upon us. Thereupon he adjured by Allah and asked if that only was the purpose of their sitting there. They said: By Allah, we are not sitting here but for this very purpose, whereupon he (the Messenger) said: I am not asking you to take an oath because of any allegation against you but for the fact that Gabriel came to me and he informed me that Allah, the Exalted and Glorious, was talking to the angels about your magnificence.
We were along with Allah's Apostle (ﷺ) on a journey when the people began to pronounce "Allahu Akbar" in a loud voice. Thereupon Allah's Messenger (ﷺ) said: O people, show mercy to yourselves for you are not calling One who is deaf or absent. Verily, you are calling One who is All-Hearing (and) Near to you and is with you. Abu Musa said that he had been behind him (the Prophet) and reciting: "There is neither might nor power but that of Allah." He (the Prophet), while addressing 'Abdullah b. Qais, said: Should I not direct you to a treasure from amongst the treasures of Paradise? I ('Abdullah b. Qais) said: Allah's Messenger, do it, of course. Thereupon he (the Prophet) said: Then recite: "There is no might and no power but that of Allah."
" There is no god but Allah, Allah is the Greatest." Thereupon Allah's Apostle (ﷺ) said: Verily, you are not supplicating One Who is deaf or absent. He said: Abu Musa or Abdullah b Qais, should I not direct you to the words (which are from) the treasures of Paradise? I said: Allah's Messenger, what are these? He said:" There is no might and no power but that of Allah."
