Reward for the Monotheists and Gnostics

“There is nothing greater in reward than testifying that: 'There is no god but Allah, because nothing equals Allah, the Mighty and High, and nobody shares His Power.'"

Messenger of Allah (sw) said: “Whoever dies without ascribing a partner to Allah, will enter Heaven regardless of whether he has done good or evil.”

Allah, Blessed and Exalted, said: "I am the most entitled of being feared and that My servant does not associate anything with Me, and I am the most entitled, if My servant does not associate anything with Me, to admit him into Paradise." And he (as) said: "Indeed, Allah, Blessed and Exalted, has sworn by His might and majesty that He will never punish the people of His monotheism with the Fire."

“Two events are inevitable: The one who died witnessing that there is no god but Allah (He is One and He has no partner with Him) will enter Paradise, and the one who died associating partners with Allah will enter Hellfire.”

“Come here, O Abu Dharr!” So I walked with him for some time. He said: Verily, the ones with much will be the ones with less. On the Day of Resurrection with the exception of those Allah has favoured. His Favour will spread to them from right to left, and from front to back. It will fill them with good. Abu Dharr says: I continued to walk with him for a while. Then he (sw) said: “Sit down here. He made me sit down in some low ground around which was stones.” He said to me, “Sit down until I return to you.” He (Abu Dharr) said: He went to a stony area until I could no longer see him. His delay was prolonged. Then I heard him coming, while saying, “Even if he fornicated and eve if he stole?” He said: When he came back, I immediately asked him, “O Prophet of Allah! May Allah make me your ransom! Who are you talking to in the stony area for I did not hear anyone answer you?” He replied, “It was Jibra’il who appeared to me in that stony area and said: `Glad tidings to your Ummah that anyone who dies without associating anything with Allah, the Mighty and High, will enter Heaven.” He (sw) added, “I asked Jibra’il: `Even if he fornicated and even if he stole?’ He replied: `Yes, and even if he drank wine.’”
The Compiler of this book says: What he means by this is that he will succeed in repentance so that he may enter Paradise.

I was with the Messenger of Allah (sw) and he said to me, “O Mu`adh! Do you know what is the right of Allah, the Mighty and High, upon His Servants?”, repeating it three times. I answered,” Allah and His Messenger know best.” The Messenger of Allah said: “The right of Allah, the Mighty and High, upon His Servants is that they should not associate anything with Him.” After that he asked, “Do you know what the right of the servants is upon Allah, the Mighty and High, when they respect His Right?” I answered, “Allah and His Messenger know best.” He (sw) said: “That He should not chastise them.” Or he (sw) said: “That He should not place them in Hell.”

The Messenger of Allah (sw) said: “He who dies without associating anything with Allah, whether he did good or evil, will enter Heaven.”
