How the Prophet slept
The Messenger of God would put his blessed right hand under his blessed right cheek. He would lie on his blessed right side facing the Qibla.
Supplication Before Sleeping
Hudhayfa (may God be pleased with him) states that, before the Prophet went to sleep, he would place his right hand under his cheek and pray this supplication: ‘Alla-humma Bis-mika Amu-tu WaAhya’ ‘O Allah (The Exalted) with Your name I die and I live’. Before going to sleep we should think of the sins we may have done and try our best not to do these again, repent and ask for God’s guidance. If you want to spend your night in worship then sleep the way our beloved Prophet slept and offer the morning prayer in congregation. You will surely gain the reward of worshipping all night, even though you were sleeping.
