Prophet Muhammad’s sleep routine:
• He used to sleep sometimes on a mattress, sometimes on a leather mat, sometimes on a mat made of palm leaves, sometimes on the floor, sometimes on a bed, sometimes on the sand, and sometimes on a black cloak.
• When he went to bed to sleep, he would say: “Allahumma bismika ahya wa amut.”
• He used to sleep on his right side, putting his right hand under his right cheek.
• When he woke up from sleep he would say: “Al-hamdu Lillah alladhi ahyana ba’d ma amatana wa ilayhi Al-nushur.
• He used to sleep during the first part of the night and get up to pray during the last part.
• His sleep was of the best length and it was the most beneficial of sleep. The doctors say that it is one-third of the night and day, namely eight hours.
