(1) بَاب كَيْفِيَّةِ خَلْقِ الْآدَمِيِّ فِي بَطْنِ أُمِّهِ وَكِتَابَةِ رِزْقِهِ وَأَجَلِهِ وَعَمَلِهِ وَشَقَاوَتِهِ وَسَعَادَتِهِ
'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.
