It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, Allah, the Blessed and Exalted, has detachments of angels who descend upon the gatherings of remembrance on earth and stay at them. So devote your mornings and evenings to the remembrance of Allah, and remember Allah yourselves as well. Whoever wishes to know what standing he has with Allah, let him look at what standing Allah has in his heart, for Allah, the Mighty and Majestic, gives the servant the same standing with Him that the servant has given Allah within himself."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Jabir (may Allah be pleased with them both) only with this chain; Umar is alone in narrating it."
