The answer may be found in a hadith narrated by Muslim: “By the One in Whose Hand is my soul, there is no man who calls his wife to his bed and she refuses, but the One Who is above the heavens [i.e. Allah] will be angry with her, until he (her husband) is pleased with her.”

It is permissible for husband and wife to masturbate each other. It is part of the enjoyment which Allah has allowed.

In Islam, Muslim spouses should say this du’a before having sex: “Bismillah, Allahumma jannibnash-shaytana wa jannib-ash-shaytana ma razaqtana.”
