Various masaail of Qurbaani

Q: What is the ruling regarding the following situation:

At the time of Qurbaani, certain stock farmers sell sheep and goats to the public. They charge a stipulated fee for providing the services of skinning the animal, slicing and parceling the meat for all those people who wish to do Qurbaani at their farm. Before the days of Qurbaani, people go to the farms, and after selecting the animals, purchase them from the farmers. After purchasing the animals they leave the animals on the farms to be slaughtered during the days of Qurbaani.

Other people merely phone the farmer and purchase their animals over the phone without going to the farm and selecting the animals. At times, the farmer selects and marks an animal for the client (e.g. sheep, goat, etc.) and concludes the transaction over the phone on the specific marked animal. At times, the sale is concluded over the phone, however the farmer does not select and mark any animal at the time of concluding the sale. Since the farmer knows that he has extra animals in the pen, he concludes the transaction on an unspecified animal with this in mind that on the day of Qurbaani, he will select an animal for the client and carry out his Qurbaani.

Is this method of purchasing the animal and carrying out the Qurbaani correct where the animal is not selected by the purchaser but by the farmer himself according to both situations explained (i.e. where the farmer concludes the sale on a specific marked animal or on an unspecified animal and only specifies it at the time of slaughter)? If this is not the correct method of purchasing, then what is the correct Shar’ee method of purchasing the Qurbaani animal and asking the farmer to slaughter it on one’s behalf?

Q: If one is slaughtering a buffalo or cattle for Qurbani, can one intend the remaining six shares for Nabi صلي الله عليه وسلم and Sahaba (Radiyallahu Anhum) as isale sawaab? What is the reward for doing so? Is there a specific reward?

Q: Question on costing for Qurbani by the committee providing the service. Is it permissible to add an extra amount to the Qurbani cost for masjid development projects. To add service charges and admin costs is understandable. But using the Qurbani as an opportunity for fund raising for the masjid is questionable. This pushes the cost of Qurbani up making it difficult to perform the duty.

Q: In my country there are organisations that do Qurbani and send the meat to needy countries, the price differs by which country it goes to. Is it ok if my husband does this as a Qurbani for himself and our son? And is it ok to choose which ever one suits our pocket?

Q: Will it be more rewarding to purchase one goat for R3000 for qurbaani (due to its size) but whose meat is hardly edible, or to buy two sheep which have good meat for the same total price?

Q: In exchange of R1000, will it be preferable for me to purchase one sheep which is large in size, or will it be preferable to purchase two standard size sheep for the same price?

Q: Can we feed a dog the bone of a qurbani animal?

Q: My question is that if in any country it is prohibited to eat cow, and if anyone slaughters a cow he gets punishment from the government, so what should Muslims do in this situation according to Islam?

Q:

1. What is the purpose of Qurbani in Shariah?
2. What are the benefits of Qurbani, how would you explain in detail to a non Muslim?

Q: Is one's qurbani valid if subsequently rumours are heard and suspicions arise that the person entrusted to perform the quarbani on one's behalf overseas has not done so?
