يُدَبِّرُ ٱلْأَمْرَ مِنَ ٱلسَّمَآءِ إِلَى ٱلْأَرْضِ ثُمَّ يَعْرُجُ إِلَيْهِ فِى يَوْمٍ كَانَ مِقْدَارُهُۥٓ أَلْفَ سَنَةٍ مِّمَّا تَعُدُّونَ ۝٥

32:5 He directeth the ordinance from the heaven unto the earth; then it ascendeth unto Him in a Day, whereof the measure is a thousand years of that ye reckon.
