How The Human Being Is Created, In His Mother's Womb, And His Provision, Lifespan And Deeds Are Written Down, And His Misery and Happiness
Sahih Muslim
حَدَّثَنِي أَبُو الطَّاهِرِ، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي عَمْرُو بْنُ الْحَارِثِ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم بِهَذَا الْمَعْنَى وَفِيهِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " كُلُّ عَامِلٍ مُيَسَّرٌ لِعَمَلِهِ " .
This hadith has been transmitted on the authority of Jabir b. Abdullah with the same wording (and includes these words): " Allah's Messenger (ﷺ) said: Every doer of deed is facilitated in his action."
