Changing one's gender

Q: Maybe I sound crazy but this is a very serious issue. I heard in Pakistan a girl became a boy naturally. This is strange, but I know Allah can do any thing. But my mind is stuck in that I don't want this with me. Is this sheaytaani waswasa? Please help me I never want to become like this. I am a girl and I am happy with that.

Participating in mixed martial arts competitions

Q: I have been practising mixed martial arts for self defence reasons, but I wonder if it's a good idea to be entered into a mixed Martial arts competition, such as the UFC and to compete and to prove Muslims are not people who can be just pushed over. We have men who are capable of physically defending ourselves. But this is something small to why I want to enter into Mixed martial arts, I want to spread Dawah, and earn fame and recognition Insha Allah to better the cause of the Ummah and the needy and the orphans and to become a spokesperson for my brothers and sisters in the realm of mixed martial arts.

Spitting in the direction of the qiblah

Q: What does the following hadith mean and is the hadith sahih?

Non-Muslim changing his name

Q: My friend has recently reverted to Islam and the question has been asked if he has to change his name or he can keep his name?

Also, he is soon to be married, Insha Allah, to a Muslim girl... if it is permissible to keep his name, does it impact the performance of the nikkah in any way?... Can the nikkah continue as normal with just his non-Arabic name?

Zakaat on Kruger coins

Q: Please advise me on whether zakat is payable on the selling price of a kruger coin or on the market value of an ounce of gold. The selling value of a kruger coin is more than the value of an ounce of gold although the kruger coin weighs an ounce.
