إِنَّ ٱللَّهَ لَهُۥ مُلْكُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ ۖ يُحْىِۦ وَيُمِيتُ ۚ وَمَا لَكُم مِّن دُونِ ٱللَّهِ مِن وَلِىٍّۢ وَلَا نَصِيرٍۢ
Lo! Allah! Unto Him belongeth the Sovereignty of the heavens and the earth. He quickeneth and He giveth death. And ye have, instead of Allah, no protecting friend nor helper.
