Qur'an 14:10

۞ قَالَتْ رُسُلُهُمْ أَفِى ٱللَّهِ شَكٌّ فَاطِرِ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۖ يَدْعُوكُمْ لِيَغْفِرَ لَكُم مِّن ذُنُوبِكُمْ وَيُؤَخِّرَكُمْ إِلَىٰٓ أَجَلٍ مُّسَمًّى ۚ قَالُوٓا۟ إِنْ أَنتُمْ إِلَّا بَشَرٌ مِّثْلُنَا تُرِيدُونَ أَن تَصُدُّونَا عَمَّا كَانَ يَعْبُدُ ءَابَآؤُنَا فَأْتُونَا بِسُلْطَـٰنٍ مُّبِينٍ

Their messengers said: Can there be doubt concerning Allah, the Creator of the heavens and the earth? He calleth you that He may forgive you your sins and reprieve you unto an appointed term. They said: Ye are but mortals like us, who would fain turn us away from what our fathers used to worship. Then bring some clear warrant.
