'Among the Believers are men who have been true in their covenant with Allah.' (33.23)

"The Messenger of Allah (ﷺ) said: 'When Allah has saved the believers from Hell and they are safe, none of you will dispute with his companion more vehemently for some right of his in this world than the believers will dispute with their Lord on behalf of their brothers in faith who have entered Hell. They will say: " Our Lord! They are our brothers, they used to pray with us, fast with us and perform Hajj with us, and you have admitted them to Hell." He will say: "Go and bring forth those whom you recognize among them." So they will come to them , and they will recognize them by their faces. The Fire will not consume their faces, although there will be some whom the Fire will seize halfway up their shins, and others whom it will seize up to their ankles. They will bring them forth, and will say. "Our Lord, we have brought forth those whom You commanded us to bring forth." Then He will say: "Bring forth those who have a Dinar's weight of faith in their hearts, then those who have half a Dinar's weight in their hearts, then those who have a mustard-seed's weight." Abu Sa'eed said. :"He who does not believe this, let him recite, 'Surely, Allah wrongs not even of the weight of an atom (or a small ant), but is there is any good (done), He doubles it, and gives from Him a great reward.'"

"The Messenger of Allah said: 'No one of you disputes more intensely for something that is rightly his in this world, than the believers will dispute with their Lord for their brothers who have entered the Fire. They will say: 'Our Lord, our brothers used to pray with us and fast with us, and perform Hajj with us, and you have caused them to enter the Fire?' He will say: 'Go and bring forth whomever you recognize among them.' So they will go to them, and will recognize them by their appearances. Among them will be those who have been seized by the Fire up to the middle of their shins, and some among them those whom it has taken up to his ankles. They will bring them forth, then they will say: 'Our Lord, we have brought forth those whom You commanded us (to bring forth).' He will say: 'Bring forth everyone in whose heart is faith the weight of a Dinar.' Then He will say: 'Everyone in whose heart is faith the weight of half a Dinar,' until He will say: 'In whose heart is faith the weight of the smallest speck.'" Abu Sa'eed said: "Whoever does not believe this, let him read the Verse: 'Verily, Allah forgives not that partners should be set up with Him (in worship), but He forgives except that (anything else) to whom He wills up to a tremendous (sin).'"

“Allah will keep firm those who believe, with the word that stands firm.” This has been revealed concerning the torment of the grave. It will be said to him: ‘Who is your Lord?’ He will say: ‘My Lord is Allah, and my Prophet is Muhammad.’ This is what Allah says: Allah will keep firm those who believe, with the word that stands firm in this world (i.e. they will keep on worshipping Allah Alone and none else), and in the Hereafter (i.e., at the time of questioning in the grave).’”

"Allah will keep firm those who believe, with the world that stands firm in this world, and in the Hereafter. This was revelated concerning the torment in the grave. It will be said to him (the deceased: 'Who is your Lord?' and he will say: 'My Lord is Allah and my Prophet is Muhammad. That is what is (the meaning of) His saying: Allah will keep firm those who believe, with the word that stands firm in this world, and in the Hereafter".
