Sahih Bukhari Volume 6, Book 65, Hadith 4949

حَدَّثَنَا يَحْيَى، حَدَّثَنَا وَكِيعٌ، عَنِ الأَعْمَشِ، عَنْ سَعْدِ بْنِ عُبَيْدَةَ، عَنْ أَبِي عَبْدِ الرَّحْمَنِ، عَنْ عَلِيٍّ ـ عَلَيْهِ السَّلاَمُ ـ قَالَ كُنَّا جُلُوسًا عِنْدَ النَّبِيِّ صلى الله عليه وسلم فَقَالَ ‏"‏ مَا مِنْكُمْ مِنْ أَحَدٍ إِلاَّ وَقَدْ كُتِبَ مَقْعَدُهُ مِنَ الْجَنَّةِ وَمَقْعَدُهُ مِنَ النَّارِ ‏"‏‏.‏ فَقُلْنَا يَا رَسُولَ اللَّهِ أَفَلاَ نَتَّكِلُ قَالَ ‏"‏ لاَ، اعْمَلُوا فَكُلٌّ مُيَسَّرٌ ‏"‏‏.‏ ثُمَّ قَرَأَ ‏{‏فَأَمَّا مَنْ أَعْطَى وَاتَّقَى * وَصَدَّقَ بِالْحُسْنَى * فَسَنُيَسِّرُهُ لِلْيُسْرَى‏}‏ إِلَى قَوْلِهِ ‏{‏فَسَنُيَسِّرُهُ لِلْعُسْرَى‏}‏

Narrated By Ali : We were in the company of the Prophet and he said, "There is none among you but has his place written for him, either in Paradise or in the Hell-Fire." We said, "O Allah's Apostle! Shall we depend (on this fact and give up work)?" He replied, "No! Carry on doing good deeds, for everybody will find easy (to do) such deeds as will lead him to his destined place." Then the Prophet recited: 'As for him who gives (in charity) and keeps his duty to Allah, and believes in the Best reward. We will make smooth for him the path of ease... the path for evil.' (92.5-10)
