The Messenger of Allah (May peace be upon him) was asked : Is it known who are those who will go to paradise and those who will go to hell? He said : Yes. He asked : Then what is the good of doing anything by those who act? He replied : Everyone is helped to do for which he has been created. (Using translation from Abū Dāʾūd 4709)
سَأَلَ رَجُلٌ رَسُولَ اللهِ ﷺ فَقَالَ يَا رَسُولَ اللهِ أَعُلِمَ أَهْلُ الْجَنَّةِ مِنَ أَهْلِ النَّارِ؟ قَالَ «نَعَمْ» قَالَ فَفِيمَ يَعْمَلُ الْعَامِلُونَ؟ قَالَ «كُلٌّ مُيَسَّرٌ لِمَا خُلِقَ لَهُ»
