Praise Allah with the praises of Entire Creation
اَلْحَمْدُ لِلّٰهِ الَّذِيْ كَفَانِيْ وَآوَانِيْ ، اَلْحَمْدُ لِلّٰهِ الَّذِيْ أَطْعَمَنِيْ وَسَقَانِيْ ، اَلْحَمْدُ لِلّٰهِ الَّذِيْ مَنَّ عَلَيَّ فَأَفْضَلَ ، اَللّٰهُمَّ إِنِّيْ أَسْأَلُكَ بِعِزَّتِكَ أَنْ تُنَجِّيَنِيْ مِنَ النَّارِ
Al-ḥamdu lillāhi-lladhī kafānī wa āwānī, al-ḥamdu lillāhi-lladhī aṭʿamanī wa saqānī, al-ḥamdu lillāhi-lladhī manna ʿalayya fa-afḍal, Allāhumma innī as’aluka biʿizzatika an tunajjiyanī mina-n-nār.
All praise is for Allah who has sufficed me and given me refuge. All praise is for Allah who has fed me and given me drink. All praise is for Allah who has been gracious to me and showered favours on me. O Allah, I ask You by Your glory to save me from the Hell-Fire.
The Messenger of Allah ﷺ said: “Whoever says [the above] when retiring to bed has praised Allah with all the praises of His entire creation.” (Hākim 2001)
