بَاب كَيْفِيَّةِ خَلْقِ الْآدَمِيِّ فِي بَطْنِ أُمِّهِ وَكِتَابَةِ رِزْقِهِ وَأَجَلِهِ وَعَمَلِهِ وَشَقَاوَتِهِ وَسَعَادَتِهِ
Sahih Muslim 2649 a

'Imran b. Husain repotted that it was said to Allah's Messenger (ﷺ):

Has there been drawn a distinction between the people of Paradise and the denizens of hell? He said: Yes. It was again said: (If it is so), then What is the use of doing good deeds? Thereupon he said: Everyone is facilitated in what has been created for him.
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ يَزِيدَ الضُّبَعِيِّ، حَدَّثَنَا مُطَرِّفٌ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، قَالَ قِيلَ يَا رَسُولَ اللَّهِ أَعُلِمَ أَهْلُ الْجَنَّةِ مِنْ أَهْلِ النَّارِ قَالَ فَقَالَ ‏"‏ نَعَمْ ‏"‏ ‏.‏ قَالَ قِيلَ فَفِيمَ يَعْمَلُ الْعَامِلُونَ قَالَ ‏"‏ كُلٌّ مُيَسَّرٌ لِمَا خُلِقَ لَهُ ‏"‏ ‏.‏
