Restraint of trade agreement

Q: I would like to know if a restraint of trade agreement is permissible in an Islamic sale.

Example: I am selling my cellphone business to Zaid. In the sale agreement a clause is added that I, the seller, is not allowed to trade in the same field of business for a stipulated period (e.g. 5 years). Will such a clause be permissible? If not will the adding of such a clause nullify the entire sale? Or will the clause be impermissible and the rest of the sale be correct?

Reciting Surah Baqarah in the home

Q: I heard a hadith of our Nabi Hazrat Muhammad (sallallahu alaihi wasallam) that a person should recite Surah Baqarah in the home.

My question is that, can I recite Surah Baqarah periodically, (30% in the morning, 30% in the afternoon and the remaining in the evening) because it is too long to be completed at a single time (morning, evening or afternoon). Is it ok or should I have to recite it at a single time?
