Covering your head while eating and drinking.
Q. Please tell me if it is sunnah to cover your head while eating, drinking water and sleeping?
A. It is mentioned that the Prophet (SAS) used to have his head covered while eating and drinking. So, it will be regarded as a Sunnah to do so.
As for sleeping, it is not reported that it is a Sunnah to cover the head while sleeping.
And Allah knows best.
