Remembrance 12 from Chapter 60
What to say when one intends to sleep and is lying in bed
Al-ḥamdu li-llāhi-lladhī kafānī wa āwānī, wa aṭ‘amanī wa saqanī, wa-lladhī manna ‘alayya fa-afḍal, wa-lladhī a‘ṭānī fa-ajzal, al-ḥamdu li-llāhi ‘alā kulli ḥāl. Allāhumma Rabba kulli shay’in wa Mālikah, wa Ilāha kulli shay’, aūdhu bika mina-n-Nār.
We relate in the Sunan of Abū Dāwūd with a ṣaḥīḥ isnād that Ibn ‘Umar 
reported that the Messenger of Allah 
used to say when he went to bed: “Praise be to Allah Who has protected me, given me refuge, fed me and given me to drink; Who has been gracious to me and showered favours on me; Who has provided for me and has been most generous. Praise be to Allah in all conditions. O Allah, Lord of all things and Sovereign and God of all things, I seek Your protection from Hell-Fire.” [21].
