How near He actually is
A measurement given in the Qur'an, in terms of your own body.
وَلَقَدْ خَلَقْنَا ٱلْإِنسَـٰنَ وَنَعْلَمُ مَا تُوَسْوِسُ بِهِۦ نَفْسُهُۥ ۖ وَنَحْنُ أَقْرَبُ إِلَيْهِ مِنْ حَبْلِ ٱلْوَرِيدِ
…wa naḥnu aqrabu ilayhi min ḥabli-l-warīd.
“And We have already created man and know what his soul whispers to him, and We are closer1 to him than [his] jugular vein.”
