Last three Surahs of the Quran

When retiring to his bed every night, The Prophet (sal-Allaahu 'alayhe wa sallam) would hold his palms together, and (whilst blowing - would) lightly spit in them, recite the last three chapters of the Quran and then wipe over his entire body as much as possible with his hands, beginning with his head and face and then all parts of the body. He would do this three times. Recite Al-Ikhlas, Al-Falaq and An-Nas

﷽
قُلۡ هُوَ اللّٰهُ اَحَدٌ‌ ۚ‏﴿١﴾ اَللّٰهُ الصَّمَدُ‌ ۚ‏﴿٢﴾ لَمۡ يَلِدۡ ۙوَلَمۡ يُوۡلَدۡ ۙ‏﴿٣﴾ وَلَمۡ يَكُنۡ لَّهٗ كُفُوًا اَحَدٌ ﴿٤﴾‏‏ ‏

With the Name of Allah, the Most Gracious, the Most Merciful. Say: He is Allah (the) One. The Self-Sufficient Master, Whom all creatures need, He begets not nor was He begotten, and there is none equal to Him

Bismillaahir-Rahmaanir-Raheem. Qul Huwallaahu 'Ahad. Allaahus-Samad. Lam yalid wa lam yoolad. Wa lam yakun lahu kufuwan 'ahad.

2.Soorah al-Falaq(113):

﷽
قُلۡ اَعُوۡذُ بِرَبِّ الۡفَلَقِۙ‏ ﴿١﴾ مِنۡ شَرِّ مَا خَلَقَۙ‏ ﴿٢﴾ وَمِنۡ شَرِّ غَاسِقٍ اِذَا وَقَبَۙ‏ ﴿٣﴾ وَمِنۡ شَرِّ النَّفّٰثٰتِ فِى الۡعُقَدِۙ‏ ﴿٤﴾ وَمِنۡ شَرِّ حَاسِدٍ اِذَا حَسَدَ ﴿٥﴾

With the Name of Allah, the Most Gracious, the Most Merciful. Say: I seek refuge with (Allah) the Lord of the daybreak, from the evil of what He has created, and from the evil of the darkening (night) as it comes with its darkness, and from the evil of those who practice witchcraft when they blow in the knots, and from the evil of the envier when he envies.

Bismillaahir-Rahmaanir-Raheem. Qul 'a'oothu birabbil-falaq. Min sharri maa khalaq. Wa min sharri ghaasiqin 'ithaa waqab. Wa min sharrin-naffaathaati fil-'uqad. Wa min sharri haasidin 'ithaa hasad.

3. Soorah al-Naas:(114)

﷽
قُلۡ اَعُوۡذُ بِرَبِّ النَّاسِۙ‏ ﴿١﴾ مَلِكِ النَّاسِۙ‏ ﴿٢﴾ اِلٰهِ النَّاسِۙ‏ ﴿٣﴾ مِنۡ شَرِّ الۡوَسۡوَاسِ ۙ الۡخَـنَّاسِ ۙ‏﴿٤﴾ الَّذِىۡ يُوَسۡوِسُ فِىۡ صُدُوۡرِ النَّاسِۙ‏ ﴿٥﴾ مِنَ الۡجِنَّةِ وَالنَّاسِ ﴿٦﴾

With the Name of Allah, the Most Gracious, the Most Merciful. Say: I seek refuge with (Allah) the Lord of mankind, the King of mankind, the God of mankind, from the evil of the whisperer who withdraws, who whispers in the breasts of mankind, of jinns and men.

Bismillaahir-Rahmaanir-Raheem. Qul 'a'oothu birabbin-naas. Malikin-naas. 'Ilaahin-naas. Min sharril-waswaasil-khannaas. Allathee yuwaswisu fee sudoorin-naas. Minal-jinnati wannaas.
