The Muslim should be devoted to being physically and spiritually pure. A Muslim has to purify the heart of all spiritual diseases and purify the body from all impurities.
Coming to your question, it should be made clear that if a woman reaches orgasm, she is required to perform ghusl even if there is no actual intercourse.
The prominent Muslim scholar Sheikh Muhammad Saleh Al-Munajjid, a prominent Muslim Saudi scholar and lecturer, states: “If seminal discharge comes out of a woman without intercourse, she has to perform ghusl. The Prophet (peace and blessings be upon him) commanded women to perform ghusl if they notice seminal discharge, as was reported by Malik in Al-Muwatta’, and by Al-Bukhari and An-Nasa’i on the authority of Umm Salamah (may Allah be pleased with her) who said: Umm Sulaym, the wife of Abu Talhah, came to the Messenger of Allah (peace and blessings of Allah be upon him) and said, “O Messenger of Allah, there should not be shyness in asking about matters of truth. Does a woman have to perform ghusl
If she has an (erotic) dream?” He said, “Yes, if she sees seminal discharge.” In this hadith, he (peace and blessings be upon him) commanded women to perform ghusl if they see seminal discharge.
Al-Baghawi said in Sharh As-Sunnah: “Ghusl for janabah (major impurity) is obligatory if either of the following applies: either the tip of the penis penetrates the vagina, or the gushing liquid is emitted by the man or the woman.” Muslim scholars said that ghusl does not become obligatory unless one is sure that the wetness one feels comes from the gushing liquid.
Ibn Qudamah said in Al-Mughni: “The Prophet (peace and blessings be upon him) connected doing ghusl to seeing (sminal discharge) when he said: “If you see the water and if the water gushed out, then perform ghusl.” The ruling does not apply otherwise.
Ibn Hajar said in Al-Fath: “This indicates that ghusl is obligatory for women, if they emit fluid at the point of climax.”
Ibn Rajab said in Al-Fath: “This hadith indicates that if a woman sees an (erotic) dream and notices the fluid when she wakes up, she has to perform ghusl. This was the view of the majority of scholars and no dissenting view is known except for that of An-Nakha`i, who holds another view.”
This hadith of the Prophet (peace and blessings be upon him) makes the matter quite clear, which is that if any fluid is emitted by the woman—whether it is a little or a lot—then she has to do ghusl.
On the basis of the above, if a woman feels that some fluid has come out of her vagina, even if it is only a little, then she has to perform ghusl, because of the report to that effect. It is not sufficient for her to do wudu’ (ablution) in this case unless the fluid which was emitted was not the kind of fluid for which ghusl is required, such as madhy (lubricating secretion), in which case wudu’ (ablution) is sufficient.”
