Narrated `Ali:

We were in the company of the Prophet (ﷺ) 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 Messenger! 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 (ﷺ) 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)

Ali reported: We were in a funeral in the graveyard of Gharqad when Allah's Messenger (ﷺ) came to us and we sat around him. He had a stick with him. He lowered his head and began to scratch the earth with his stick, and then said: There is not one amongst you whom a seat in Paradise or Hell has not been allotted and about whom it has not been written down whether he would be an evil person or a blessed person. A person said: Allah's Messenger, should we not then depend upon our destiny and abandon our deeds? Thereupon he said: Acts of everyone will be facilitated in that which has been created for him so that whoever belongs to the company of the blessed will have good works made easier for him and whoever belongs to the unfortunate ones will have evil acts made easier for him. He then recited this verse (from the Qur'an): "Then, who gives to the needy and guards against evil and accepts the excellent (the truth of Islam and the path of righteousness it prescribes), We shall make easy for him the easy end and who is miserly and considers himself above need, We shall make easy for him the difficult end" (xcii. 5-10).
