عَنْ حُذَيْفَةَ بْنِ اليَمَانِ رَضيَ اللهُ عنه:
أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ إِذَا أَرَادَ أَنْ يَنَامَ وَضَعَ يَدَهُ تَحْتَ رَأْسِهِ، ثُمَّ قَالَ: «اللَّهُمَّ قِنِي عَذَابَكَ يَوْمَ تَجْمَعُ أَوْ تَبْعَثُ عِبَادَكَ».
[صحيح] - [رواه الترمذي] - [سنن الترمذي: 3398]

Hudhayfah ibn al-Yamān (may Allah be pleased with him) reported:
When the Prophet (may Allah's peace and blessings be upon him) intended to sleep, he would place his hand under his head, then say: "Allāhumma qini ‘adhābaka yawma tajma‘u or tab‘athu ‘ibādak (O Allah, protect me from Your punishment on the Day You gather or resurrect Your servants)."
[Authentic hadith] - [Narrated by At-Termedhy - An-Nasaa’i - Narrated by Abu Daoud - Narrated by Ahmad] - [Sunan At-Termedhy - 3398]
When the Prophet (may Allah's peace and blessings be upon him) lay down to sleep, he would rest his head on his right hand and place his right cheek upon it, and he would say: "O Allah" my Lord, "protect me" and guard me against "Your punishment" and torment "on the Day You gather or resurrect Your servants" for reckoning, i.e., the Day of Judgment.
