Narrated `Aisha: Whenever Allah's Apostle went to bed, he used to recite Surat-al-Ikhlas, Surat-al-Falaq and Surat-an- Nas and then blow on his palms and pass them over his face and those parts of his body that his hands could reach. And when he fell ill, he used to order me to do like that for him.

Narrated 'Aisha: Whenever the Prophet (saws) went to bed every night, he used to cup his hands together and blow over it after reciting Surat Al-Ikhlas, Surat Al-Falaq and Surat An-Nas, and then rub his hands over whatever parts of his body he was able to rub, starting with his head, face and front of his body. He used to do that three times.

Narrated Usaid bin Hudair: That while he was reciting Surat Al-Baqara (The Cow) at night, and his horse was tied beside him, the horse was suddenly startled and troubled. When he stopped reciting, the horse became quiet, and when he started again, the horse was startled again. Then he stopped reciting and the horse became quiet too. He started reciting again and the horse was startled and troubled once again. Then he stopped reciting and his son, Yahya was beside the horse. He was afraid that the horse might trample on him. When he took the boy away and looked towards the sky, he could not see it. The next morning he informed the Prophet who said, "Recite, O Ibn Hudair! Recite, O Ibn Hudair!" Ibn Hudair replied, "O Allah's Apostle! My son, Yahya was near the horse and I was afraid that it might trample on him, so I looked towards the sky, and went to him. When I looked at the sky, I saw something like a cloud containing what looked like lamps, so I went out in order not to see it." The Prophet said, "Do you know what that was?" Ibn Hudair replied, "No." The Prophet said, "Those were Angels who came near to you for your voice and if you had kept on reciting till dawn, it would have remained there till morning when people would have seen it as it would not have disappeared.
