Allah narrates to us the arguments that ensued between the disbelievers and their Messengers. When their nations doubted the Message of worshipping Allah alone without partners, the Messengers said,

[أَفِى اللَّهِ شَكٌّ]

((What!) Can there be a doubt about Allah...) about His Lordship and having the exclusive right to be worshipped alone, being the only Creator of all creatures Verily, none besides Allah is worthy of worship, alone without partners with Him. Most nations were, and still are, affirming the existence of the Creator, but they call upon intermediaries besides Him whom they think will benefit them or bring them closer to Allah. Their Messengers said to them,

[يَدْعُوكُمْ لِيَغْفِرَ لَكُمْ مِّن ذُنُوبِكُمْ]

(He calls you that He may forgive you of your sins) in the Hereafter,

[وَيُؤَخِّرْكُمْ إِلَى أَجَلٍ مُّسَمًّى]

(and give you respite for a term appointed.), in this worldly life. Allah said in other Ayat,

[وَأَنِ اسْتَغْفِرُواْ رَبَّكُمْ ثُمَّ تُوبُواْ إِلَيْهِ يُمَتِّعْكُمْ مَّتَاعًا حَسَنًا إِلَى أَجَلٍ مُّسَمًّى وَيُؤْتِ كُلَّ ذِي فَضْلٍ فَضْلَهُ]

(Seek the forgiveness of your Lord, and turn to Him in repentance, that He may grant you good enjoyment, for a term appointed, and bestow His abounding grace to every owner of grace.) [10:3] However, their nations went on arguing against their prophethood, after they had to submit to the first evidence (that Allah Alone created everything).
