An adult daughter and father, or brother and sister, sleeping in one bed
Question
What is the ruling of the Shari‘a on an adult daughter lying down and sleeping together with her father on one rope bed or in one bed? Likewise, how is it according to the Shari‘a for an adult brother and sister, and likewise an adult son and his father, to lie down and sleep together? If it is contrary to the Shari‘a, what are the forms and kinds of divine reproach?
Answer
It is by no means permitted; they should all sleep separately. The noble hadith states: when children become discerning, separate their beds. The consequence of acting against the noble hadith is bad here and bad in the Hereafter as well.
