Making qadha of salaahs from the time one's haidh ends

Q: I am at the end of menses and I saw discoloured discharge at the end of asr, a few minutes before maghrib was about to begin. The next time I checked was the next morning after sunrise, 6 hours before zuhr - this time I saw clear discharge. I waited until zuhr/asr to check again to ensure my menses had truly ended. I then did ghusl at asr and made qada of zuhr and fajr. Do I have to make qada of the previous days asr, maghrib and isha prayers?

Qnet

Q: I would like to enquire regarding the Shar’ee ruling of a certain business scheme that is currently being promoted in many places of this country and in other countries as well. The scheme operates under the name “Qnet.” I will explain how this scheme works through an example: 

Zaid purchases a watch from Qnet for the amount of R40,000. However, this type of watch is normally sold for approximately R1,000 in the general market. The only reason why Zaid purchases this watch at such an inflated price is to gain entry into the Qnet business scheme and start earning profits. 

Zaid then refers others (Bakr, Khalid, and Qaasim) to also purchase a watch from Qnet at a similar inflated price. Once these individuals make their purchases of the watches, Zaid immediately receives a commission for referring them. 

Subsequently, Bakr, Khalid, and Qaasim each proceed to recruit five more individuals to the Qnet scheme. When these new recruits make purchases from Qnet, Zaid, as well as Bakr, Khalid, and Qaasim, respectively, receive further commission based on these purchases. Though Zaid did not make any effort in getting the five more individuals to purchase and join Qnet, he receives a commission from their purchases. 

Each of these five individuals will then get ten more people to purchase from Qnet. When these fifty new people purchase from Qnet, then Zaid, Bakr, Khalid and Qaasim as well as the five individuals respectively will receive commission from the fifty new people. This chain will continue down the line and those on top will continue receiving commission from the transactions that take place at the bottom, even though they do not make any effort. 

Is participation in such a business scheme permissible in Islam?
