Answered by Shaykh Yūsuf Badāt
Is it objectionable for spouses to view each other’s private parts?
In the Name of Allāh, Most Merciful, Most Compassionate
Jazāk Allāh Khayr/ Thank you for your question.
It is Islamicaly permissible for a husband and wife to see each other’s private parts for pleasure or any other reason. There is no objection in this.
The only relationship wherein sexual intimacy is allowed is the relationship of husband and wife. When intercourse is permissible, then surely it is permissible for a married couple to enjoy each other by fondling, touching or seeing each other.
Saʿd ibn Masʿūd al-Kandī reported, ʿOthmān ibn Maʾdhūn (may Allāh be pleased with him) came to Allāh’s Messenger (peace and blessings upon him) and said, ‘Messenger of Allāh (peace and blessings upon him), I feel embarrassed when my wife looks at my private parts (ʿawrah).’ The Messenger (peace and blessings upon him) said, ‘Allāh has made you (husbands) a garment for them (wives) and made them a garment for you.’” (Muṣannaf ʿAbd al-Razzāq)
Even though this is permissible, the Prophet (peace and blessings upon him) preferred to avoid glancing or seeing the private organs of his spouse. (See: Tirmidhī)
And Allāh Knows Best
