It was narrated that 'Ali (رضي الله عنه) said: One day the Messenger of Allah ﷺ was sitting with a stick in his hand, with which he was hitting the ground. He raised his head and said: 'There is no soul among you but his place in Paradise or Hell is known". They said: O Messenger of Allah ﷺ, why should we strive? He said: 'Keep striving for everyone will be helped to do that for which he was created. As for him who gives (in charity) and keeps his duty to Allah and fears Him. And believes in Al-Husna. Al-Husna: The Best (ie either la ilaha illallah: none has the right to be worshipped but Allah) or a reward from Allah (ie Allah will compensate him for what he will spend in Allah's way or bless him with Paradise) We will make smooth for him the path of ease (goodness). But he who is greedy miser and thinks himself self-sufficient, And belies Al-Husna, We will make smooth for him the path for evil, al-Lail 92:5-10'.
