Narrated Anas bin Malik : Allah's Apostle ( صلى الله عليه و آله وسلم ) said, "When (Allah's - سبحانہ و تعا لی) slave is put in his grave and his companions return and he even hears their footsteps, two angels come to him and make him sit and ask, 'What you used to say about this person (i.e. Prophet Muhammad - صلى الله عليه و آله وسلم - by showing his picture)?' The faithful Believer will say, 'I testify that he is Allah's ( سبحانہ و تعا لی) 'Abd' and His Apostle -صلى الله عليه و آله وسلم ).' Then they will say to him, 'Look at your place in the Hell Fire; Allah ( سبحانہ و تعا لی) has given you a place in Paradise instead of it.' So he will see both his places." (Qatada said, "We were informed that his grave would be made spacious." Then Qatada went back to the narration of Anas who said;) Whereas a hypocrite or a non-believer will be asked, "What did you use to say about this man." He will reply, "I do not know; but I used to say what the people used to say." So they will say to him, "Neither did you know nor did you take the guidance." Then he will be hit with iron hammers once, that he will send such a cry as everything near to him will hear, except Jinns and human beings. (Bukhari - Volume 2, Book 23, number 456).
