وَ هُوَ الَّذِىۡ خَلَقَ السَّمٰوٰتِ وَالۡاَرۡضَ فِىۡ سِتَّةِ اَ يَّامٍ وَّكَانَ عَرۡشُهٗ عَلَى الۡمَآءِ لِيَبۡلُوَكُمۡ اَيُّكُمۡ اَحۡسَنُ عَمَلًا ؕ وَلَٮِٕنۡ قُلۡتَ اِنَّكُمۡ مَّبۡعُوۡثُوۡنَ مِنۡۢ بَعۡدِ الۡمَوۡتِ لَيَـقُوۡلَنَّ الَّذِيۡنَ كَفَرُوۡۤا اِنۡ هٰذَاۤ اِلَّا سِحۡرٌ مُّبِيۡنٌ(هود :7)
Wahuwa allathee khalaqa alssamawati waalarda fee sittati ayyamin wakana 'arshuhu 'ala almai liyabluwakum ayyukum ahsanu 'amalan walain qulta innakum mab'oothoona min ba'di almawti layaqoolanna allatheena kafaroo in hatha illa sihrun mubeenun
And it is He who created the heavens and the earth in six days - and His Throne had been upon water - that He might test you as to which of you is best in deed. But if you say, "Indeed, you are resurrected after death," those who disbelieve will surely say, "This is not but obvious magic."
