Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
It is not permissible for a man or a woman to use sexual toys, because this is considered as masturbation, and worse than masturbation.
Anyway, if these toys are used individually, or it is the husband who is using them with his wife or vice versa, it is not permissible. And it is not permissible at all to buy or sell these toys, because it is a way of helping in Haram things. Allah Says (interpretation of meaning): {…but do not help one another in sin and transgression….}[5:2].If these toys represent or contain a picture (photographs) of living beings, they are Haram, as they are statues. A Fatwa about statues and photography has been issued. Please refer to Fatwa:83314
So, this ruling applies to using sex toys to achieve ejaculation. If they are used for other purposes, we cannot give a ruling until we know the details.
Allah knows best.
