Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "Allah the Exalted says: 'I am as my slave expects me to be, and I am with him when he remembers Me. If he remembers Me inwardly, I will remember him inwardly, and if he remembers Me in an assembly, I will remember him in a better assembly (i.e., in the assembly of angels)."

[Al-Bukhari and Muslim].

وعن أبي هريرة، رضي الله عنه، أن رسول الله ﷺ، قال: "يقول الله تعالى: أنا عند ظن عبدي بي، وأنا معه إذا ذكرني، فإن ذكرني في نفسه، ذكرته في نفسي وإن ذكرني في ملإٍ ذكرته في ملإٍ خير منهم" ((متفق عليه)).
