Sahih Muslim Book 40, Hadith Number 6873.
Chapter : The reckoning on the Day of judgment is a fact.
‘Aisha reported Allah’s Apostle (may peace be upon him) as saying: Everyone who is reckoned thoroughly is undone. I said: Allah’s Messenger, has Allah not called (reckoning) as easy reckoning? Thereupon he said.. It implies only presentation of (one’s deeds to Him), but if one is thoroughly examined in reckoning, he in fact is undone.
