Of the issues that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, taught Ali, Alayhi al-Salam, as advice were the following: O Ali, you must not go to bed with your wife in the first night of a lunar month, in the night of the middle of the month, and in the last night of the month, because it is feared for the child of insanity (being possessed by Jinn).’ Ali, Alayhi al-Salam, asked, ‘Why is it, O Messenger of Allah?’ He (the Messenger of Allah) replied, ‘It is because Jinn frequent overwhelming their women in the first night of a lunar month, in the night of the middle of the month and in the last night of the month. Have you not seen that one possessed by Jinn becomes epileptic in beginning of the month, in the end and in the middle of the night?”’
