Musnad Abi Ya'la 4137 — the Messenger of Allah ﷺ said: I will knock

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I will knock at the gate of Paradise, and a gate of gold will be opened for me whose ring is of silver. Then a mighty light will receive me, and I will fall down in prostration and offer such praise and glorification of Allah Almighty as no one before me will have offered. Then it will be said to me: Raise your head; ask and you will be given, intercede and your intercession will be accepted, and speak and your words will be heard. I will say: O my Lord! My Ummah. Then it will be said: Yours is every person (entitled to enter Paradise) who has faith equal to a grain of barley in his heart. He (peace and blessings be upon him) said: Then I will prostrate a second time and offer (praise and glorification) in the same way again, and say: My Ummah. Then it will be said to me: Yours is the one who has faith equal to a mustard seed in his heart. Then I will prostrate a third time and again offer (praise and glorification) in the same way, and the same thing will be said to me. Then I will raise my head and say: My Ummah. Then it will be said: Yours is the person who said 'La ilaha illallah' (There is none worthy of worship except Allah) with sincerity of heart."
