" Commentary : This verse takes up the most important and the most fundamental issue of the Qur'an, which is monotheism by explaining the campaign against polytheism as follows: Allah's first and foremost call to mankind is that he should stop worshipping everything else but the Almighty. The verse says: "(It teaches)that you should worship none but Allah.
..." Secondly, the Divine call concerns the matter that the Prophet(p.b.u.h.) is surely acting on Allah's behalf, as a messenger of warning and glad tidings. The duty of the Prophet(p.b.u.h.) is that he warns people against disobeying Allah, injustice, corruption, polytheism and infidelity. He informs them of Divine punishment as a result of their evil actions, and give them glad tidings of a happy fate for their obedience, piety and virtuousness. The holy verse continued saying: "...
But if you turn away(from serving Him), then I fear for you the Penalty of a Great Day. " Commentary : His third call is that people should repent from their sins, and purify themselves from all types of pollution. His fourth call for them is that they should turn to Him after purifying themselves from their sins by repentance, thus decorating themselves with Divine characteristics. This means that returning to Him means nothing more than acquiring those qualities that are associated with Him.
Afterwards, the holy Qur'an recounts that the practical results which ensue from acceptance or rejection of the four commandments, mentioned in the above, are as follows: Whenever you act according to this schedule, Allah grants you a whole happy life- time of enjoyment in your worldly life.
