Sahih Bukhari Volume 6, Book 65, Hadith 4951

حَدَّثَنَا آدَمُ، حَدَّثَنَا شُعْبَةُ، عَنِ الأَعْمَشِ، قَالَ سَمِعْتُ سَعْدَ بْنَ عُبَيْدَةَ، يُحَدِّثُ عَنْ أَبِي عَبْدِ الرَّحْمَنِ السُّلَمِيِّ، عَنْ عَلِيٍّ ـ رضى الله عنه ـ قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم فِي جَنَازَةٍ فَأَخَذَ شَيْئًا فَجَعَلَ يَنْكُتُ بِهِ الأَرْضَ فَقَالَ ‏"‏ مَا مِنْكُمْ مِنْ أَحَدٍ إِلاَّ وَقَدْ كُتِبَ مَقْعَدُهُ مِنَ النَّارِ وَمَقْعَدُهُ مِنَ الْجَنَّةِ ‏"‏‏.‏ قَالُوا يَا رَسُولَ اللَّهِ أَفَلاَ نَتَّكِلُ عَلَى كِتَابِنَا وَنَدَعُ الْعَمَلَ قَالَ ‏"‏ اعْمَلُوا فَكُلٌّ مُيَسَّرٌ لِمَا خُلِقَ لَهُ، أَمَّا مَنْ كَانَ مِنْ أَهْلِ السَّعَادَةِ فَيُيَسَّرُ لِعَمَلِ أَهْلِ السَّعَادَةِ، وَأَمَّا مَنْ كَانَ مِنْ أَهْلِ الشَّقَاءِ فَيُيَسَّرُ لِعَمَلِ أَهْلِ الشَّقَاوَةِ ‏"‏‏.‏ ثُمَّ قَرَأَ ‏{‏فَأَمَّا مَنْ أَعْطَى وَاتَّقَى * وَصَدَّقَ بِالْحُسْنَى‏}‏ الآيَةَ‏.‏

Narrated By Ali : While the Prophet was in a funeral procession. he picked up something and started scraping the ground with it, and said, "There is none among you but has his place written for him either in the Hell Fire or in Paradise." They said, "O Allah's Apostle! Shall we not depend upon what has been written for us and give up deeds? He said, "Carry on doing (good) deeds, for everybody will find easy to do such deeds as will lead him to his destined place for which he has been created. So he who is destined to be among the happy (in the Hereafter), will find it easy to do the deeds characteristic of such people, while he who is destined to be among the miserable ones, will find it easy to do the deeds characteristic of such people." Then he recited: 'As for him who gives (in charity) and fears Allah, and believes in the best...' (92.5-10)
