Q 1: Why does Islam prohibit a brother and sister from sleeping together?
(Part No. 26; Page No. 337
The Prophet (peace be upon him) prohibited
brothers and sisters to sleep in the same bed under one cover, in his statement: "Command your children to perform Salah (prayer) when they are seven years old, and beat them for (not offering) it when they are ten, and do not let (boys and girls) sleep together." This is because at this age males begin to feel inclined to females and vice versa, along with lacking sound reasoning. Satan may be able to induce them to commit what is unlawful.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
