Ramadhaan & Fasting

Fasting qadha fasts in Shawwaal

Q: I missed two days of fasting in Ramadhaan due to menstruation and I have missed 15 days of fasting from the previous Ramadhaans. In order to obtain the reward of fasting six days in Shawwal, must I make up all 17 fasts first or only two?

In addition to this I forgot to keep the intention for some of the fasts of Ramadhaan, must I make an estimate and make up these fasts? If yes then should I do this also before fasting the six days of Shawwal?

Father discharging sadaqatul fitr on behalf of his baaligh children

Q: Will sadaqatul fitr be discharged if the father discharged it on behalf of his baaligh children (who have above the nisaab amount but he still looks after them) but they were only informed that the sadaqatul fitr was discharged in their behalf a few days after Ramadan ended. He pays their sadaqatul fitr every year but forgot to actually mention it to them this year before discharging it.

Not fasting in the month of Ramadhaan on account of taking part in a soccer event

Q: The company I work for hosts a soccer event once a year for all African countries and this year the event falls in Ramadaan. They have tried their best to look for alternate dates but because there will be 700 participants they cannot get get accommodation at any other time. They are very concerned about the +/- 15 Muslim participants and the ruling regarding fasting for these travellers from Senegal and Ivory Coast.

Please can you advise on the correct ruling regarding exemption in this regard.
