Murabaḥah is a term for a sales contract where the buyer and seller agree on the markup, the ratio between the cost of a good or service and what?
Murabaha Murabaḥah, murabaḥa or murâbaḥah (Arabic: مرابحة‎ ‎ , derived from "ribh" Arabic: ربح‎ ‎ , meaning profit) is a term of "fiqh" (Islamic jurisprudence) for a sales contract where the buyer and seller agree on the markup (profit) or "cost-plus" price for the item(s) being sold. In recent decades it has become a term for a very common form of Islamic (i.e. "shariah compliant") financing, where the price is marked-up in exchange for allowing the buyer to defer payment (a contract with deferred payment being known as "bai-muajjal"). "Murabaha" financing is similar to a rent-to-own arrangement in the non-Muslim world, with the intermediary (i.e. the lending bank) retaining ownership of the item being sold until the loan is paid in full. There are also Islamic investment funds and sukuk (Islamic bonds) that use "murabahah" contracts.
Sabr Sabr (Arabic: صَبْرٌ‎ , "ṣabr " ‎ ) is the Islamic virtue of "patience" or "endurance" or more accurately "perseverance" and "persistence". "Ṣabr" is characterized as being one of the two parts of faith (the other being "shukr"). It teaches to remain spiritually steadfast, and to keep doing good actions in the personal and collective domain, specifically when facing opposition or encountering problems, setbacks, or unexpected and unwanted results.It is patience in face of all unexpected and unwanted outcome.
