Mu'jam Kabir Tabarani 3867 — the Messenger of Allah ﷺ came out to them

It is narrated from Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) came out to them and said: "My Lord, the Mighty and Majestic, gave me the choice between seventy thousand entering Paradise with forgiveness, without reckoning, or instead a handful (granted to me) from Him." A man said: O Messenger of Allah, will your Lord give you a handful? So the Messenger of Allah (peace and blessings be upon him) went inside, then came out to them saying the takbir, and said: "My Lord, the Mighty and Majestic, has given me more: with every thousand there will be seventy thousand more, and the handful with Him besides." Abu Ruhm (may Allah have mercy on him) said: O Abu Ayyub, what do you think the handful of Allah is? At this the people set upon him with their tongues, so Abu Ayyub (may Allah be pleased with him) said: Leave your companion alone. I will tell you about the handful of the Prophet (peace and blessings be upon him), as I think, rather as one who is certain: the handful of the Prophet (peace and blessings be upon him) is that he (peace and blessings be upon him) says: "O my Lord, whoever bears witness that there is no god but You, alone, You have no partner, and that Muhammad is Your servant and Messenger, and then his heart confirms his tongue, Paradise becomes obligatory for him."
