First: We should contemplate and ponder the purpose of our creation.
Say (to them O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ): "I exhort you to one (thing) only: that you stand up for Allâh's sake in pairs and singly, and reflect (within yourselves the life history of the Prophet ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ)
Verily! In the creation of the heavens and the earth, and in the alternation of night and day, there are indeed signs for men of understanding. Those who remember Allâh (always, and in prayers) standing, sitting, and lying down on their sides, and think deeply about the creation of the heavens and the earth, (saying): "Our Lord! You have not created (all) this without purpose, glory to You! (Exalted are You above all that they associate with You as partners). Give us salvation from the torment of the Fire.
Does man think that he will be left neglected (without being punished or rewarded for the obligatory duties enjoined by his Lord Allâh on him)?
That is, they are forgotten and disregarded, receiving no command or prohibition. Every Muslim knows with certainty that they have not been created without a purpose; yet, they have been created to worship Allah alone and to show obedience to Him and to His Messenger (peace be upon him).
And I (Allâh) created not the jinn and mankind except that they should worship Me (Alone).
O mankind! Worship your Lord (Allâh), Who created you and those who were before you so that you may become AlMuttaqûn (the pious See V.2:2).
Allah (Glorified be He) commands all humankind and Jinn to fulfill the purpose for which they have been created, and He sent messengers and revealed books to convey and demonstrate this purpose and call people to it.
And they were commanded not, but that they should worship Allâh, and worship none but Him Alone (abstaining from ascribing partners to Him), and perform AsSalât (Iqâmata sSalât) and give Zakât
And verily, We have sent among every Ummah (community, nation) a Messenger (proclaiming): "Worship Allâh (Alone), and avoid (or keep away from) Tâghût (all false deities i.e. do not worship Tâghût besides Allâh)."
Worship Allâh and join none with Him (in worship)
This (Qur'an) is a Message for mankind (and a clear proof against them), in order that they may be warned thereby, and that they may know that He is the only One Ilâh (God Allâh) (none has the right to be worshipped but Allâh) and that men of understanding may take heed.
Thus, all those who sincerely seek good for themselves should attach the greatest importance to the purpose of their creation and give it precedence over anything else; and they should beware of preferring the worldly life to the hereafter, their whims to guidance and the obedience of their own souls and Satan to the obedience of Allah, the AllMerciful King.
Then for him who transgressed all bounds, (in disbelief, oppression and evil deeds of disobedience to Allâh). And preferred the life of this world (by following his evil desires and lusts), Verily, his abode will be Hellfire;
But as for him who feared standing before his Lord, and restrained himself from impure evil desires and lusts. Verily, Paradise will be his abode.
