Sayyidina Abdullah ibn Khubayb narrated: We went out on a rainy, extremely dark night seeking Allah’s Messenger i, that he might lead us in salah. I found him. He said to me, “Say!” But I did not say anything. Then he said, “Say!” Again, I did not say anything. Once again he said, “Say!” I asked, “What shall I say?” He said, “Say: Say: He is Allah the One and Only. (112:1) (Surah al-Ikhlas) al-Falaq and an-Naas when you are in the evening and in the morning, three times. This will suffice you in everything.” [Abu Dawud 5082, Nisai 5443]
