Are you in doubt about the Resurrection?.

     Allah, the Exalted, says in Surat Almu'menuon Aya 115: did you then think that We had created you uselessly (without purpose) and that you would not brought back to us?.  And He said about Himself: "it is He who created death and life, that He may test you as to which of you excels in doing good deeds (is better), and He is the All-mighty, the Forgiving (Almulk:2).

   

     Here Allah Azza wa Galla has mentioned death before life, the reason of that seems to be that death or non-existence is the state that comes before life. in other words, everything that came into existence was the beginning in a state of lifelessness or non-existence, then it was awarded life. 

    So the purpose of creating death and life is test us, this test is more important and is of greater significance in death rather than in life, because the one who thinks of death constantly will have the tendency to do more and more righteous deeds. The thought of death, however is most effective in correcting one's conduct . 

     Allah said to His Messenger Muhammad (PBUH), that He too is to die and so are His friends and foes, who will also die: "You will surely die, and so shall they (Alzumur:30)", the objective behind the statement is to alert and persuade everyone to be concerned about the hereafter and to be ready to do everything necessary to achieve the goal. Although the prophet Muhammad is the most sublime among the creation and the foremost among prophets, He is not exempted from death, and Allah said to Him: "then, on the day of Resurrection, you will all dispute one with another before your Lord (Alzumar: 31)".

       The believer has no doubt about the day of resurrection, but disbelievers and polytheists says as Allah Azza wa Gall has told us in the Holy Quran: ''can it be possible that when we are deed and reduced to dust and bones we shall be raised to life again? and shall our forefathers of earlier times be also?, here Allah, Almighty, directly answers their questions saying: yes and you shall then be disgraced (humiliated), then there shall be but a single driving shout (cry) and behold! they will be up and looking on".

     And in Surat Alhajj ayah 5, there is an evidence of the Resurrection in the creation of man and of plants, when Allah speaks of disbelief in the Resurrection, He also mention the evidence of His power and ability to resurrect that is evident from the way He initiates creation, that He says:" O people, if you are in doubt about the Resurrection, We have indeed created you from dust, then from a semen-drop, then from clinging substance, and then from an embryonic lump, formed and unformed, that we may show you (make clear to you), and We settle in the wombs whom we will, for a specified term, then We bring you out as a child, and then He develop you that you may reach your time of maturity and among you is he who is dies, and among you is he who is returned to the most decrepit old age so that he knows after once having knowledge nothing, and you see the earth barren, but when We send down upon it rain, it gets stirred and it swells and grows of every beautiful kind.
