It is narrated on the authority of 'Uthman that the Messenger of Allah (ﷺ) said. He who died knowing (fully well) that there is no god but Allah entered Paradise.

We were accompanying the Apostle (ﷺ) in a march (towards Tabuk). He (the narrator) said: The provisions with the people were almost depleted. He (the narrator) said: (And the situation became so critical) that they (the men of the army) decided to slaughter some of their camels. He (the narrator) said: Upon this Umar said: Messenger of Allah, I wish that you should pool together what has been left out of the provisions with the people and then invoke (the blessings of) Allah upon it. He (the narrator) said: He (the Holy Prophet) did it accordingly. He (the narrator) said: The one who had wheat in his possession came there with wheat. He who had dates with him came there with dates. And Mujahid said: He who possessed stones of dates came there with stones. I (the narrator) said: What did they do with the date-stones. They said: They (the people) sucked them and then drank water over them. He (the narrator said): He (the Holy Prophet) invoked the blessings (of Allah) upon them (provisions). He (the narrator) said: (And there was such a miraculous increase in the stocks) that the people replenished their provisions fully. He (the narrator) said: At that time he (the Holy Prophet) said: I bear testimony to the fact that there is no god but Allah, and I am His messenger. The bondsman who would meet Allah without entertaining any doubt about these (two fundamentals) would enter heaven.

He who said: There is no god but Allah, He is One and there is no associate with Him, that Muhammad is his servant and His messenger, that Christ is servant and the son of His slave-girl and he (Christ) His word which He communicated to Mary and is His Spirit, that Paradise is a fact and Hell is a fact, Allah would make him (he who affirms these truths enter Paradise through any one of its eight doors which he would like.

Allow me some time (so that I may talk with you). Why do you weep? By Allah, if I am asked to bear witness, I would certainly testify for you (that you are a believer). Should I be asked to intercede, I would certainly intercede for you, and if I have the power, I would certainly do good to you, and then observed: By Allah, never did I hear anything from the Messenger of Allah (ﷺ) which could have been a source of benefit to you and then not conveyed it to you except this single hadith. That I intend to narrate to you today, since I am going to breathe my last. I heard the Messenger of Allah (ﷺ) say: He who testifies that there is no god but Allah and that Muhammad is the messenger of Allah, Allah would prohibit the fire of Hell for him.

I was riding behind the Prophet (ﷺ) and there was nothing between him and me but the rear part of the saddle, when he said: Mu'adh b. Jabal: To which I replied: At your beck and call, and at your pleasure, Messenger of Allah! He moved along for a few minutes, when again he said: Mu'adh b. Jabal: To which I replied: At your beck and call, and at your pleasure, Messenger of Allah! He then again moved along for a few minutes and said: Mu'adh b. Jabal: To which I replied. At your beck and call, and at your pleasure. Messenger of Allah He, (the Holy Prophet) said: Do you know what right has Allah upon His servants? I said: Allah and His Messenger know best. He (the Holy Prophet) said: Verily the right of Allah over His servants is that they should worship Him, not associating anything with Him. He (the Holy Prophet) with Mu'adh behind him, moved along for a few minutes and said: Mu'adh b. Jabal: To which I replied: At your beck and call, and at your pleasure, Messenger of Allah! He (the Holy Prophet) said: Do you know what rights have servants upon Allah in case they do it (i. e. they worship Allah without associating anything with Him)? I (Mu'adh b. Jabal) replied: Allah and His Messenger know best. (Upon this) he (the Holy Prophet) remarked: That He would not torment them (with the fire of Hell).

We were sitting around the Messenger of Allah (may peace and blessings be upon him). Abu Bakr and Umar were also there among the audience. In the meanwhile the Messenger of Allah got up and left us, He delayed in coming back to us, which caused anxiety that he might be attacked by some enemy when we were not with him; so being alarmed we got up. I was the first to be alarmed. I, therefore, went out to look for the Messenger of Allah (may peace and blessings be upon him) and came to a garden belonging to the Banu an-Najjar, a section of the Ansar went round it looking for a gate but failed to find one. Seeing a rabi' (i. e. streamlet) flowing into the garden from a well outside, drew myself together, like a fox, and slinked into (the place) where God's Messenger was. He (the Holy Prophet) said: Is it Abu Huraira? I (Abu Huraira) replied: Yes, Messenger of Allah. He (the Holy Prophet) said: What is the matter with you? replied: You were amongst us but got up and went away and delayed for a time, so fearing that you might be attacked by some enemy when we were not with you, we became alarmed. I was the first to be alarmed. So when I came to this garden, I drew myself together as a fox does, and these people are following me. He addressed me as Abu Huraira and gave me his sandals and said: Take away these sandals of mine, and when you meet anyone outside this garden who testifies that there is no god but Allah, being assured of it in his heart, gladden him by announcing that he shall go to Paradise. Now the first one I met was Umar. He asked: What are these sandals, Abu Huraira? I replied: These are the sandals of the Messenger of Allah with which he has sent me to gladden anyone I meet who testifies that there is no god but Allah, being assured of it in his heart, with the announcement that he would go to Paradise. Thereupon 'Umar struck me on the breast and I fell on my back. He then said: Go back, Abu Huraira, So I returned to the Messenger of Allah (ﷺ), and was about to break into tears. 'Umar followed me closely and there he was behind me. The Messenger of Allah (may peace and blessings be on him) said: What is the matter with you, Abu Huraira? I said: I happened to meet 'Umar and conveyed to him the message with which you sent me. He struck me on my breast which made me fall down upon my back and ordered me to go back. Upon this the Messenger of Allah (ﷺ) said: What prompted you to do this, 'Umar? He said: Messenger of Allah, my mother and father be sacrificed to thee, did you send Abu Huraira with your sandals to gladden anyone he met and who testified that there is no god but Allah, and being assured of it in his heart, with the tidings that he would go to Paradise? He said: Yes. Umar said: Please do it not, for I am afraid that people will trust in it alone; let them go on doing (good) deeds. The Messenger of Allah (ﷺ) said: Well, let them.
