Carry on doing (good deeds)
Narrated `Ali may Allah be pleased with him:
We were in the company of the Prophet ( may the peace and blessings of Allah be upon him ) in a funeral procession at Baqi Al-Gharqad. He said, "There is none of you but has his place written for him in Paradise or in the Hell- Fire." They said, "O Allah's Apostle! Shall we depend (on this fact and give up work)?" He said, " Carry on doing (good deeds), for every body will find it easy to do (what will lead him to his destined place)." Then he ( may the peace and blessings of Allah be upon him ) recited: 'As for him who gives (in charity) and keeps his duty to Allah, and believes in the Best reward from Allah (i.e. Allah will compensate him for what he will spend in Allah's way). So, We will make easy for him the path of ease. But he who is a greedy miser....for him, the path for evil.' (92.5-10)
Believing in the decree of Allah is one of the pillars of faith. The one who did not believe in the decree of Allah, he did not really believe in his oneness, nor in his perfection.
This is because the decree is one of the things that are peculiar to Allah and no one other than him knows it.
The decree of Allah: is his fair predestination in all that He created.
He knows what happened, what is happening and what will happen. The decree of Allah is based on his vast knowledge which encompassed everything. No one can resist his judgment. No one knows what Allah is capable of. Therefore no one may deny or discuss the details of the divine decree lest one will end up with falling in the doubts.
Every one is guided to fulfill the purpose for which he was created. Everyone will be facilitated to go to the abode in which he will reside either the Paradise or the Hell fire.
The slave has to do his best to please his Lord but he is not obliged to fulfill all the demands of his slave. Dear Muslim brother please note that the means are in the hands of Allah the Almighty and that he will respond to those who ask him.
