﴿ ۞ قَالَتْ رُسُلُهُمْ أَفِى ٱللَّهِ شَكٌّۭ فَاطِرِ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ ۖ يَدْعُوكُمْ لِيَغْفِرَ لَكُم مِّن ذُنُوبِكُمْ وَيُؤَخِّرَكُمْ إِلَىٰٓ أَجَلٍۢ مُّسَمًّۭى ۚ قَالُوٓا۟ إِنْ أَنتُمْ إِلَّا بَشَرٌۭ مِّثْلُنَا تُرِيدُونَ أَن تَصُدُّونَا عَمَّا كَانَ يَعْبُدُ ءَابَآؤُنَا فَأْتُونَا بِسُلْطَٰنٍۢ مُّبِينٍۢ ﴾

“Said the apostles sent unto them: "Can there be any doubt about [the existence and oneness of] God, the Originator of the heavens and the earth? It is He who calls unto you, so that He may forgive you [whatever is past] of your sins and grant you respite until a term [set by Him is fulfilled]." [But] they replied: "You are nothing but mortal men like ourselves! You want to turn us away from what our forefathers were wont to worship: well, then, bring us a clear proof [of your being God's message-bearers]!"”

'Can there be doubt concerning God, despite the obviousness of Himḍ In other words, how can you doubt that to which we [the messengers] are calling you to when there is no room for doubt concerning Him on account of the extent of His manifestnessḍ Rather it is that it is necessary to clarify that which clarifies Him. He calls you so that He might forgive you your sins, so that He might shield by His light the darkness of the veils of your attributes so that you do not have any doubt concerning Him at the disclosure of certainty, and defer you to, a felicitous end entailed by your preparedness, since every individual has designated for him, in accordance with his first preparedness, a perfection which constitutes his spiritual term. Likewise for every person, in accordance with his first constitution, there is an end to his life that constitutes his natural term. And just as interfering terms severe life before arrival at that appointed end because of some particular cause, likewise calamities and impediments, which are the veils of preparedness, prevent a person from arriving at that designated perfection.
