From Sahih Muslim (Hadith 7227):
A'isha reported Allah's Apostle (ﷺ) 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 presenta- tion of (one's deeds to Him), but if one is thoroughly examined in reckoning, he in fact is undone
