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.
The Messenger of Allah (ﷺ) said to his Companions: “Say ‘Glory is to Allah and with His Praise (Subḥān Allāh, wa biḥamdih)’ a hundred times. Whoever says will forgive him.”
