Responding to this, Sheikh Salim `Abdus-Salam Ash-Shaykhi, da`iyah, states:

Buying in installment is two types:
1- When there are two people a buyer and a seller. In this case it is permitted to buy in installments according to all scholars except Shaik Albani and his opinion is rejected.
2) When there are three sides involved; a buyer, a seller and a finance company. Most of this type is haram, since the seller receives all his cost from the finance company. The buyer then pays installments that include interest to the financing company and this is Riba and haram.
