Using black dye

Q: When explaining the maslah of Khidaab, my teacher said the following (In his own words):

Within Ahnaaf, there is two qowls on whether you can do black khidaab for beauty (zeenat)

1. According to some, it isn't permissable at all, it is haraam.

2. A lot of muftiyaani karaam and people of fataawa have given the fatwah of jawaaz. (This is excluding the situation when an old man has married a young women, because in this situation it is permissibile to do black khidaab, and this is the qowl of nearly all the fuqahaa).

My question is, do the Hanafiyah actually have the second qowl mentioned above? From what I have read on your website and ask imam, black khidaab isn't permissible. He also mentioned that Allahmah Ibnul Qayim has wrote a list of the Sahaabah radiyallahu anhum who would do black khidaab in zaadul ma'aad.

Hosting a soccer tournaments for Hifz students

Q: If we have a soccer tournament amongst our students from the Hifz class in my area.

1. After the tournament can a reward be given for the winner or rather can a reward be given to all the particapants for their participation in the event?

2. If rewards can be given, can we give medals?

3. Thirdly, the tournament is held in a private arena and a males only event. Entry is denied to any player who does not comply to a dress code requirement; 3 quarter shorts, etc.

Keeping the above in mind, do the Ulama advise having soccer tournaments for Hifz boys? Is it against the Mizaaj of Shariat?
