The mugharribun are they who do not mention Allah when they have sexual intercourse with their wives. One should not neglect to pray at the time of sexual intercourse.
وَعَنْ عَائِشَةَ قَالَتْ: قَالَ لِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «هَلْ رُئِيَ فِيكُمُ الْمُغَرِّبُونَ؟» قُلْتُ: وَمَا الْمُغَرِّبُونَ؟ قَالَ: «الَّذِينَ يَشْتَرِكُ فِيهِمُ الْجِنُّ» . رَوَاهُ أَبُو دَاوُد
‘A’isha told that God’s messenger asked her, “Have the mugharribun been seen among you?” She asked what that meant and he replied, “They are those in whom is a strain of the jinn.”* Abu Dawud transmitted it.
* Mirqat, iv, 514, says this happens if a man neglects to mention God when he has sexual intercourse with his wife.
