Selling R5 airtime for R6

Q: At my work place, we sell airtime from machines. Because of the very low profit margin, my employer wants to, for example, sell the R5 at R6 and increase the other denominations accordingly. Will this be permissible according to Shari’ah?

Signing conditions to approve the loan

Q: A certain person owns a business and is the landlord at the same time. He decides to sell the business and lease out the property to the person who bought his business. The bank is loaning the buyer the money to purchase the business. The bank requests that the seller of the business (who is also the landlord) sign a document in which he agrees that if the purchaser of the business defaults, then the bank has the right to take over the lease (in other words, they will continue to pay the landlord rent until they find someone to purchase the business from them).

Is it permissible for the seller of the business to sign this agreement with the bank?

How was Hazrat Bilal (Radiyallahu Anhu) tortured?

Q: I have read about how Hazrat Bilal (Radiyallahu Anhu) was tortured. I have read that he was tortured by:

  1. Made to lie on hot desert sand.
  2. Thrown into boiling water.
  3. Dragged through the streets with ropes. 

Are these three types of torture proven from authentic ahadith? What other ways do the Ahadith mention about how Hazrat Bilal (Radiyallhu Anhu) was tortured?

Disclosing health problems when getting one's children married

Q: My girls have some health problems like thyroid and cholesterol. Do I need to disclose them or hide them at the time of their marraige. Since my marriage is in trouble and my husband is against marrying the girls early, what would be appropriate for me to do? I feel that our house is not favorable for them to flourish and they don't have any social life and they are Alhamdu-Lillah very good girls. They already suffer my health issues and our divorce issues since they are 5. I want to marry them early (early teen) so that they can lead pious lives.
