Sunan Ibn Majah Book 35, Hadith 6
“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.’”
“The Messenger of Allah (ﷺ) said: ‘A righteous dream is one of the seventy parts of prophecy.’”
“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.’”
