Abu Hurairah reported,

The Messenger of Allah ﷺ said that Allah عز وجل says, "I am as My servant thinks of Me, and I am with him whenever he remembers Me. If he remembers Me within himself, I remember him within Myself. If he remembers Me in a gathering, I remember him in a better gathering. If he draws near to Me by a handspan, I draw near to him by a cubit. If he draws near to Me by a cubit, I draw near to him by an arm's length. And if he comes to Me walking, I come to him running."

Muslim 6832

عن أبي هريرة قال

قال رسول الله ﷺ يقول الله عز وجل أنا عند ظن عبدي وأنا معه حين يذكرني فإن ذكرني في نفسه ذكرته في نفسي وإن ذكرني في ملإ ذكرته في ملإ خير منه وإن اقترب إلي شبرا تقربت إليه ذراعا وإن اقترب إلي ذراعا اقتربت إليه باعا وإن أتاني يمشي أتيته هرولة
