Abu Huraira
narrated that Rasul Allah
said, “Allah swt says I am closer to my slave than his supposition of which he keeps of me. And when he/her does Zikr of Allah, I am with him/her. If he does Zikr in his heart, I do his Zikr near MY proximity (closeness) and if he does Zikr in a gathering, I mention him in a gathering Afdhal (better) than it. (Bukhari)
