It is narrated from Mujahid (may Allah have mercy on him): «﴿وَتَذَرُونَ مَا خَلَقَ لَكُمْ رَبُّكُمْ مِنْ أَزْوَاجِكُمْ ......﴾» [الشعراء: 166/26] That is: "You leave what Allah Almighty has created for you in the form of your wives." Mujahid (may Allah have mercy on him) said: By Allah, what is meant by this is the private part (vagina) of the woman.
