Muslim

Anas bin Malik (RA) reported Allah's Messenger (ﷺ) as saying: Allah, the Exalted and High, would say to one who shall have to undergo the least torture (on the Day of Resurrection): Would you like to go as ransom if you had all worldly riches; he would say: Yes. Allah would say to him: When you were in the loins of Adam, I demanded from you something easier than this that you should not associate anything with Me. (The narrator says): I think He also said: I would not cause you to enter Hell-Fire but you defied and attributed Divinity (to others besides Me).

This hadith has been narrated on the authority of Anas bin Malik (RA) through another chain of transmitters, but with a slight variation of wording (and the words are): "I shall cause him to enter Hell." (The words subsequent to these) have not been mentioned.

Anas bin Malik (RA) reported that Allah's Messenger (ﷺ) said: It would be said to the non-believers on the Day of Resurrection: If you were to possess gold, filling the whole earth, would you like to secure your freedom by paying that? He would say: Yes. Thereupon it would be said to him: Something easier (than this) was demanded from you (but you paid no heed to it).

Anas reported this hadlth through another chain of transmitters and the words are: "It would be said to him: You have told a lie; what had been demanded from you was quite easier than this (the belief in the Oneness of Allah)."
