With regards to directing the bed towards the qiblah, is it obligatory or is it Sunnah?
Shaykh ʿAbd al-Azīz bin ʿAbdullah bin Bāz:
It is not obligatory. If he wills, he may sleep in direction of the qiblah, and if he wills, he may sleep in another direction. All praise is due to Allah ﷻ, this matter is spacious (lenient).
