Ethics of Sleeping

Endeavour to seek for Allāh's protection before sleeping. Here are some neccesary things to consider:

• Sleep with Wuḍūʾ (Ablution)
• Recite Āyatul Kursiyy (Q2:255)
• Recite Sūratul Ikhlāṣ (Q112)
• Recite Sūratul falaq (Q113)
• Recite Sūratun Nās (Q114)
• Recite Sūratul Fātiḥah (Q1)

These practices help to calm the mind, seek protection, and cultivate gratitude before rest.

Prayer before sleeping

Sleeping is a temporary death in Islām, so before sleeping, you should say "Allāhumma bismika amūtu wa aḥyā" "O Allāh in your name I die and live".
By reciting this prayer before sleep is a beautiful way to acknowledge Allāh's control over life & death, and to seek His protection & blessings during rest.

Prayer When Awake

Give thanks to Allāh (God) when you awake by saying "Alḥamdulillahi ladhī aḥyānā baʿda mā amātanā wa ilayhin nushūr" "Praise be to Allāh Who has given us life after He has caused us to die, and to him is the return".
