Inevitability of Allah's Will

هَلْ يَنظُرُونَ إِلَّآ أَن يَأْتِيَهُمُ ٱللَّهُ فِى ظُلَلٍ مِّنَ ٱلْغَمَامِ وَٱلْمَلَـٰٓئِكَةُ وَقُضِىَ ٱلْأَمْرُ ۚ وَإِلَى ٱللَّهِ تُرْجَعُ ٱلْأُمُورُ

Do they await but that Allāh should come to them in covers of clouds and the angels [as well] and the matter is [then] decided? And to Allāh [all] matters are returned.
