Abu Hurairah (May Allah be pleased with him) reported:
Messenger of Allah ﷺ said, "He who sees me in his dream will see me in his wakefulness (or he ﷺ may have said it is as though he has seen me in a state of wakefulness), for Satan does not appear in my form."
[Al-Bukhari and Muslim].
وعنه قال: قال رسول الله ﷺ:
"من رآني في المنام فسيراني في اليقظة -أو كأنما رآني في اليقظة- لا يتمثل الشيطان بي" .
