I have been married 8 years. Now my age is 32 and my wife is nearly 30 years old. She is sufferring from weekness and inemia for nearly 3 years. I want to have sex with her but she refuses. We can only have sex one time in a Month. And also i cant afford to marry again. Can i do masterbation to satisfy my sex deaire/need? If it is done in battles to satisfy needs, why we cannot do in private life...

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, sallallaahu 'alayhi wa sallam, is His slave and Messenger.

Masturbation is a forbidden pernicious habit. The fact that your wife does not satisfy you sexually because she is too weak to have an intercourse is not an excuse to commit what is forbidden (masturbation). You can always resort to something permissible, like making your wife masturbate for you using her hand or to enjoy her body until you satisfy your sexual need.

For more benefit on the prohibition of masturbation, please refer to Fataawa 179859, 376036, 87952, 81167, and 88957.

Allah knows best.
