Sahih al-Bukhari 3:45
Narrated Ibn Abu Mulaika:
Whenever `Aisha (the wife of the Prophet) heard anything which she did not understand, she used to ask again till she understood it completely. Aisha said: "Once the Prophet (ﷺ) said, "Whoever will be called to account (about his deeds on the Day of Resurrection) will surely be punished." I said, "Doesn't Allah say: "He surely will receive an easy reckoning." (84.8) The Prophet (ﷺ) replied, "This means only the presentation of the accounts but whoever will be argued about his account, will certainly be ruined."

حَدَّثَنَا سَعِيدُ بْنُ أَبِي مَرْيَمَ، قَالَ أَخْبَرَنَا نَافِعُ بْنُ عُمَرَ، قَالَ حَدَّثَنِي ابْنُ أَبِي مُلَيْكَةَ، أَنَّ عَائِشَةَ، زَوْجَ النَّبِيِّ صلى الله عليه وسلم كَانَتْ لاَ تَسْمَعُ شَيْئًا لاَ تَعْرِفُهُ إِلاَّ رَاجَعَتْ فِيهِ حَتَّى تَعْرِفَهُ، وَأَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " مَنْ حُوسِبَ عُذِّبَ ". قَالَتْ عَائِشَةُ فَقُلْتُ أَوَ لَيْسَ يَقُولُ اللَّهُ تَعَالَى {فَسَوْفَ يُحَاسَبُ حِسَابًا يَسِيرًا} قَالَتْ فَقَالَ " إِنَّمَا ذَلِكَ الْعَرْضُ، وَلَكِنْ مَنْ نُوقِشَ الْحِسَابَ يَهْلِكْ ".
