Sunan Ibn Majah Book 35, Hadith 7
“The Messenger of Allah (ﷺ)
drew
aside the curtain when he was sick, and the rows (of worshippers)
were behind Abu Bakr. He said: ‘O people, nothing of the glad
tidings
of prophecy is left except a good dream that a Muslim sees or
is seen
about him.’”
“I asked the Messenger of Allah (ﷺ) the about the Saying of Allah, Glorious is He: ‘For them are glad tidings, in the life of the present world, and in the Hereafter.” He said: ‘Those are good dreams that a Muslim sees or are seen about him.’”
“Whoever sees me in a dream, has seen me in reality, for Satan cannot appear in my form.”
