Questioned asked to the Permanent Committee of Scholars:
Q. What is the ruling on listening to the Qur'aan from the radio while having relations with one's wife. That which I have within myself regarding this affair while I'm in this state, is that it repels the accursed Shaytaan from the home?
A. The Prophet (sallallaahu alayhi wa sallam) has indeed taught his nation that which is to be said during the time of the man having relations with his wife. On the authority of Abdillaah Ibn Abbaas (may Allaah pleased with them both) said that the Messenger of Allaah (sallallaahu alayhi wa sallam) said:
"As for, if one of you were to say at the time when he approaches his wife - Bis millaah Allaahumma Jan nib nash Shaytaan wajan nibish Shaytaan Maa Ra zaq ta naa- (In the name of Allaah, Oh Allaah keep us away from the Shaytaan and keep theShaytaan away from that which you provide us with), if it is decreed that a child will come from that union, the Shaytaan will never be able to harm it." (Agreed Upon).
That which is specifically binding upon the individual, is the restriction (of himself) to that which has come (in the text). Indeed, the listening to the Qur'aan from the radio during the time of having relations for the purpose of repelling the Shaytaan from the home is going beyond that which is legislated. Therefore, it is not permissible. The Magnificent Qur'aan has more of a noble status and greater sanctity than to be listened to during this situation that has been mentioned. Allaah knows best and with Allaahis the success. May the Salaah of Allaah and His Salaam be upon His Prophet, his family, followers and companions."
