Business and Dealings

Q: My grandfather has several children. He had bought some pieces of land on his 3 eldest sons' names. While he was alive he sold two of the plots of land of those two sons' marriage expenditures, but kept the third plot as it is. 

Also, my grandfather did not buy land for his remaining children, but he however left behind a house without a will. 

Now, my grandfather is no more. The 3rd plot of land was bought on my father's name and is still on his name. But my father's siblings are now asking for a share in his plot of land. 

My question is whether they are entitled to any share in my father's land?

Q: Please advise the best ways (most recommended ways) to spend/dispose of interest money earned from a bank savings account?

Q: If one took a riba based loan, and he repents, should he repay only the capital portions of the loan or also the interest on the loan?

Q: A person asked me to make a credit card and provide him, he would be responsible for all credit card matters i.e. fees/charges and in return, he would pay me an amount of 1000 dollars. And I will pay 1000 dollars back in 12 equal monthly installments. I will not use the credit card benefits. Is this deal ok in the light of Islam?

Q: I provided and fitted blinds for the municipality for R100 000. However, they are not paying me despite several claims. I have lost how of receiving payment. Can I use municipal water for this value in lieu of the debt? I fill my tanks at night from a municipal line at night without getting billed.

Q: I sell 1m lengths of pipe at R80. I purchase these ready cut. I have a marking on my counter to measure 1m. Those who purchase don't specifically require 1m but purchase the metre as that's how it's sold. It is advertised as 1m. I noticed a pipe today that was marginally short. I therefore refunded R2 to the customer but did not inform him why. The pipe will still fulfill the function for which it was purchased. What is the ruling regarding this transaction?

Q: Please advise on whether it's permissible to study a cannabis course and learn about cannabis. 

Also, is it permissible sell cannabis and cannabis products for medicinal use?

Q: A member of our community as an heir would like to know if it's permissible to pay off gambling debts accrued by the deceased to pay off multiple gambling debts accrued to Muslims and non Muslims. 

Notes: 

1. A member of family has come forward to assist with these debts as they too want to rid of their unwanted interest income in order to assist with paying off these debts. 

2. The deceased does have an income deriving property asset in his estate but the income is little to none and will take years to save and accumulate the funds required to pay off the gambling debts.

Q: Is it permissible for the Imaam of the Masjid or any scholar to teach hifdh/madressa in the Masjid & charge fees? 

If not, should this be moved outside the Masjid boundary or what would be the best possible solution?
