Sahih Muslim Book 40, Hadith Number 6871.
Chapter : The reckoning on the Day of judgment is a fact.
‘Aisha reported that Allah’s Messenger (may peace be upon him) said: He who is taken to account on the Day of Resurrection is in fact put to torment. I said: Has Allah, the Exalted and Glorious, not said this: ‘He will be made subject to an easy reckoning” (ixxxiv. 8)? Thereupon he said: (What it implies) is not the actual reckoning, but only the presentation of one’s deeds to Him. He who is thoroughly examined in reckoning is put to torment.
