When about to sleep
The Prophet (sal-Allaahu 'alayhe wa sallam) would place his right hand under his cheek when about to sleep and supplicate:
اللّٰهُمَّ قِنِيْ عَذَابَكَ يَوْمَ تَبْعَثُ عِبَادَكَ
O Allah, protect me from Your punishment on the day Your servants are resurrected.'
Allaahumma qinee 'athaabaka yawma tab'athu 'ibaadaka.
|
اللّٰهُمَّ |
قِنِيْ |
عَذَابَكَ |
|
O Allah |
protect me from |
your punishment |
|
يَوْمَ |
تَبْعَثُ |
عِبَادَكَ |
|
on the day |
you resurrect |
your servants |
Abu Dawud 4/311, Sahih At-Tirmizi 3/143.
