Chapter
Narrated Ar-Rubai bint Muauwidh:
The Prophet (ﷺ) came to me the night my marriage was consummated and sat down on my bed as you (the sub-narrator) are sitting now, and small girls were beating the tambourine and singing in lamentation of my father who had been killed on the day of the battle of Badr. Then one of the girls said, "There is a Prophet amongst us who knows what will happen tomorrow." The Prophet (ﷺ) said (to her)," Do not say this, but go on saying what you have spoken before."
