Earning by viewing adverts online

Q: I am doing online work. The process of this work is that they have websites where we can work. They have the process that first we have to choose the package. I have chosen a package of 1000 rupees. It is a silver package. I have to see ads daily. One ad for one day. 1 ad will give me 60 rupees. This package is valid for 30 days. I will make 1800 rupees from there by watching ads daily on this website. After a month I can withdraw this amount in my easy paisa account. They cut out some service charges and give me 1700 or something. So I wanna know that if this money is halal for me or haram?

Selling livestock without taking possession of the livestock

Q: I've been doing livestock for the past year, I wholesale and retail livestock throughout the year and I try to do everything in the best of my ability and in the halaal way.

Yesterday I came across someone who told me the way I'm running my business is haraam.

I'm From Durban and I get livestock from Northern Cape, Free State and Eastern Cape. So when I wholesale throughout the year as customers want animals, I order from the different farmers and get it delivered directly to the customer. The farmer will send me a video, I will send the video to my customer and if he is happy then I will confirm the order with the farmer and get it delivered to the customer.

Qurbani time the farmers know that I take alot more animals so they call me or video call me and tell me they have this amount of animals for me and keep it aside. Basically they book it for me and as I get customers I call them and tell them to send this amount of animals from my lot to the customers location. I haven't personally seen the animals. The farmer does send me videos and video calls me and I don't have time to go and see them.

Is it permissible the way I trade? If not, then all the money I earned and consumed is haraam and how do I go about fixing this issue? Please advise me.

Selling chickens by weight

Q: My question is regarding weighing. I work in a shop where halaal meat is sold. They sometimes put offers on. For example, 3lb weight chicken breast boneless. The actual weight is maybe 50g for example less because the meat is cleaned from excess fat for the benefit of the customer.

My question is the butchers clean the chicken from excess fat beforehand and put on display. They then give them that chicken less the 50g or so from the 3lb weight. My heart tells me this is not right but maybe it is. Could you please let me know?

Taking possession of an item before selling it

Q: I want to sell items (mostly food) via social media. e.g. tubs of biscuits, sweetmeats, pastries etc. I do not make these items nor keep any on hand i.e. made to order. The items will be procured from multiple home vendors. I will advertise these items via social media and interested parties will contact me to order and pay me for the items. I will then order the items for the buyer and the buyer will collect from me or from known pickup points in different areas. I will be paid before I have the items in my possession and I will pay the baker once I collect/receive the items.

Will I need to get the order, buy/pay and have the item in hand before I accept funds from the buyer? Will this type of model be permissible? If not, what will I need to adjust in my model for it to be permissible?
