Can we sleep on the floor without any blanket in our home?
بسم الله الرحمن الرحيم
(Fatwa: 755/755/M=06/1435)
You may sleep at home on the floor without putting on a blanket; there is no harm in it. If there is possibility that the satr shall be uncovered during sleep then you should tie the lungi etc from the end and sleep carefully. If you mean something else then explain it completely and submit the question again.
Allah knows Best!
