What he said with his hand under his cheek
The last thing before sleep, in the position of sleep.
اللَّهُمَّ قِنِي عَذَابَكَ يَوْمَ تَبْعَثُ - أَوْ تَجْمَعُ - عِبَادَكَ
Allāhumma qinī ʿadhābaka yawma tabʿathu ʿibādak
“O Allah, protect me from Your punishment on the Day You raise Your servants.”
Where this comes from
Ibn Masʿūd describes the posture exactly. He would lie down, put his right hand under his cheek, and say this. Sleep is the small version of the thing being asked about. You lie down not certain you will be the one to get up.
The full narration
It was narrated from 'Abdullah that:whenever the Prophet (saas) went to his bed, he would put his hand - meaning his right hand - beneath his cheek then say: "Allahumma qini 'adhabaka yawm tab'athu - [or: tajma'u] - 'ibadaka (O Allah, save me from Your punishment on the Day when You resurrect - or gather - Your slaves)
