Can all Muslims answer the questions of the two angels, and will whoever is unable to answer be tormented then enter Paradise, and will the committed Muslim who died committing a minor sin be judged only by his last deed?

The torment and bliss of the grave, and the questioning by the two angels, are established by texts and consensus. Their precise nature should not be delved into, as the intellect cannot grasp it. The two believers answer the angels' questions by affirming that their Lord is Allah and their Prophet is Muhammad, whereupon the believer sees his place in Paradise. As for the torment of the grave, some of it is perpetual for disbelievers and some disobedient individuals, while some of it ceases for those who committed minor transgressions among the disobedient. The disbeliever is exposed to the Fire morning and evening. Disobedient Muslims will enter Paradise through intercession or after torment, while he who dies upon a sin less than major ones is under Allah's will. Endings are the inheritance of beginnings, which is why the predecessors feared a bad ending and asked Allah for steadfastness. The wisdom behind this is to keep the believer adhering to the sacred law and sincere to Allah until death.
