Anas reported God’s messenger as saying, “When a man is placed in his grave and his friends leave him, he hears the beat of their sandals. Then two angels come to him and, having made him sit up, they say, ‘What was your opinion of this man, of Muhammad?’ The believer replies, ‘I testify that he is God’s servant and messenger.’ He is then told to look at his abode in hell for which God has substituted for him an abode in paradise, and he sees them both. The hypocrite and infidel are asked, ‘What was your opinion of this man?’ and reply, ‘I do not know; I held the opinion others held.’ They will retort, ‘You neither knew nor did you follow [the believers].’ He will then be given a blow with iron hammers and will utter a shout which will be heard by all who are near him, with the exception of men and jinn.” (Bukhari and Muslim. The wording is Bukhari’s.)
