If a unmarried girl imagine to do intercource with her future husband is it haraam?(she is not engaged yet. She doesn't imagine any face of a man and doesn't imagine any private part of a man She just think she will wear western dress and present herself to her husband. And she imagine her husband will play with her private parts) She does not touch her private parts during imagination. she just fell down bed and imagine she is with her future husband. Is it count as Masturbation??? She does this practice once day. During imagination she reach at her climax point. That's way she performs ghusl and offer prayer. Her parents is trying for her marriage but succeed yet. Is she doing Haraam practice?

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. {C}

If a girl imagines sexual relationship as in the example that is mentioned in the question and reaches her climax point, then this is included in the forbidden masturbation based on the meaning of the verse in which Allah Says (what means): {And they who guard their private parts. Except from their wives or those their right hands possess, for indeed, they will not be blamed.} [Quran 23: 6-5] It is a method of masturbation.

It is proven in the Sunnah that imagining Zina (fornication or adultery), in a way that the person gives in to it until it settles in his heart, is a kind of Zina and the person is held accountable for it.

Abu Hurayrah narrated that the Prophet said: "The child of Aadam will have his share of Zina no matter how well he/she endeavors to avoid it. The Zina of the eyes is by gazing, the Zina of the ears is by listening, the Zina of the tongue is by talking, the Zina of the hands is by touching, the Zina of the foot is by walking (to forbidden places), and the heart desires and wishes. Then, the private parts either submit to this or deny it." [Muslim]

Mulla Ali Al-Qaari said in Mirqaat Al-Mafaateeh Sharh Mishkaat Al-Masaabeeh:

"This proves that if the wish is settled in one’s inner self, and the person insists on it, and he does not repel it, then this is called Zina. So it is a disobedience, and it entails punishment, even if one did not act; so be mindful of this.” [End of quote]

This girl should strive in supplicating Allah to facilitate for her to marry a pious husband. She is permitted to look for him and seek the help of righteous women and her trustworthy relatives, to help her in this regard.

For more benefit about the permissibility of a woman proposing to men for marriage, please refer to Fatwa 82471.

Until Allah facilitates her marriage, she should be keen on fasting, as this suppresses desires and brings piety to the heart. She should keep company with righteous women and busy herself during her free time with what benefit her in her religion and her worldly life.

Allah knows best.
