Muslims should read the Al Falaq and Annas chapters of the Quran every night and day to guard against witchcraft and demons, today's sermon tells worshippers.
"Al Falaq and Annas are suras that protect people who fear others, and calm their worries," the sermon says. "They are also the advice of the Prophet for whoever seeks good things and a way out from hardships."
The two chapters translate to The Daybreak and The Mankind.
The Prophet Mohammed once said: "O you do not know that last night certain Aya [verse]were revealed the like of which there is no precedence. They are: 'I seek refuge with the lord of the dawn' and 'Say: I seek refuge with the lord of men'."
His wife Lady Aisha said that every night, when the Prophet would go to bed, he would join his hands, blow in them, and recite: "Say: He is Allah, the One", "Say: I seek refuge in the lord of Al Falaq" and "Say: I seek refuge in the lord of mankind."
He would then wipe as much as he was able to off his body, beginning with his head and face, and the front of his body. He would do this three times.
The sermon continues: "Al Falaq advises us to seek Allah's protection from some evils, such as blowing in knots."
This refers to black magic or any similar practice, such as predicting the future or fortune-telling.
The Prophet Mohammed warned of the great sins involved in such practices: "Whoever ties a knot and blows on it, he has practised magic; and whoever practises magic, he has committed shirk; and whoever hangs up something [such as an amulet] will be entrusted to it."
