Reciting Surat al-Ikhlaas, Al-Falaq and An-Nas before sleeping
A’ishah (radi Allahu anha) said that whenever the Prophet (sal Allahu alaihi wa sallam) would go to bed every night, he would put his palms together and blow into them. Then he would recite into them (his palms), ‘Say: He is Allah, One’, ‘Say: I seek refuge with the Lord of Al-Falaq’, and ‘Say: I seek refuge with the Lord of mankind.’ Then he would wipe whatever he was able to of his body with them (his palms). He would begin wiping his head and face with them and the front part of his body. He would do this (wiping his body) three times.
We benefit from the above Hadith that we should recite these three great Surahs from the Qur’an before we go to sleep every night seeking through them the protection of Allah in whose hands alone is the ability to prevent harm and give protection.
And Allah knows best!
