Is a Muslim is allowed to look at his wife naked, and vice-versa, while fasting, if they can prevent themselves from having intercourse?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

It is lawful for the husband and wife to look at one another while naked if they are certain that this will not lead to what can spoil the fasting.

For more benefit, please refer to Fatwa 84129.

Allah knows best.
