Hadith on Sleep: Clean your bed, lie on your right side, supplicate

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “When one of you goes to his bed, let him clean his bed with his garment, for he does not know what was left upon it. Then let him say: By your name, O Lord, I place my side and by you I rise. If you take my soul, have mercy on me. If you send it back, protect it with the protection of your righteous servants.”

In another narration, the Prophet said, “Let him lie down on his right side.”

عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا أَوَى أَحَدُكُمْ إِلَى فِرَاشِهِ فَلْيَنْفُضْ فِرَاشَهُ بِدَاخِلَةِ إِزَارِهِ فَإِنَّهُ لَا يَدْرِي مَا خَلَفَهُ عَلَيْهِ ثُمَّ يَقُولُ بِاسْمِكَ رَبِّ وَضَعْتُ جَنْبِي وَبِكَ أَرْفَعُهُ إِنْ أَمْسَكْتَ نَفْسِي فَارْحَمْهَا وَإِنْ أَرْسَلْتَهَا فَاحْفَظْهَا بِمَا تَحْفَظُ بِهِ عِبَادَكَ الصَّالِحِينَ
