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.
Muktzeh Muktzeh (Hebrew: מוקצה; also transliterated as muktzah, and either spelling without the ending -h) is a Hebrew word that means "separated", or "set aside". The generally accepted view regarding these items is that they may be touched though not moved during Shabbat (the Jewish Sabbath) or Yom Tov (Jewish holiday). Some extend this prohibition to the actual handling of these items. Halakha defines various categories of objects or substances which are "set aside" on the Jewish Sabbath, as well as various permissible instances of moving these various "muktzeh" items. For example, one may not handle money, rocks, twigs, etc. on Shabbat, as these items are "muktzeh".
