وَلِلَّهِ غَيْبُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَإِلَيْهِ يُرْجَعُ ٱلْأَمْرُ كُلُّهُۥ فَٱعْبُدْهُ وَتَوَكَّلْ عَلَيْهِ ۚ وَمَا رَبُّكَ بِغَٰفِلٍ عَمَّا تَعْمَلُونَ
And Allah's is the Invisible of the heavens and the earth, and unto Him the whole matter will be returned. So worship Him and put thy trust in Him. Lo! thy Lord is not unaware of what ye (mortals) do.
