Literally: 'aqada means to tightly bind, knot, combine, make stable and permanent.
Technically: there are two meanings: general: the intention to do, regardless of whether the act results from an individual will or requires two wills to bring it into existence, like a sale, lease, agency or mortgage. This connotation is the same as commitment to do something. The specific meaning is: linkage of an offer and its acceptance in a legal manner, such that its consequences take effect upon it subject.
Literally: a baggage or commercial good. Everything is an 'ard except money, which is called 'ayn.
Technically: is defined by jurists to be any property other than money; it includes plants, animals, real estate, and all other types of property.

Literally: an exchange of property for property or an exchange without qualification.
Technically: the exchange of any property of value (i.e, lawful] (mal mutaqawwam) for another such item so that ownership of each item is transferred to the other party or to permanently exchange the ownership of a tangible asset or a permissible benefit for financial compensation.
Literally: daman: to put something into something that contains it. Standing surety is derived from this meaning because the guarantor encompasses the obligor's liability and adds it to his own.
Technically: daman is used by jurists to mean standing surety (kafalah). Therefore, they defined guarantee as: merging of one liability with another in respect or demand for performance of an obligation. Alternatively: to assume responsibility for the financial obligation of another, or to ensure the appearance of the person liable for it, or of a guaranteed commodity. Jurists also use it to refer to an unrestricted commitment; for instance, to undertake responsibility for the compensation of a destroyed tangible asset. This is what in meant the hadith "[Entitlement to] profit goes with responsibility". It also includes a guarantee to do the stipulated work in a labour partnership and to entitle the financial compensation in a credit partnership. The technical meaning of daman is more general that that of kafalah. The types of daman vary depending on the financial transaction to which it is applied.

Literally: dayn is any future liability on a person, without it being in any particular form, money or something else.

Literally: poverty (faqr) is a cleft in something; and a faqir is a person with a broken vertebra.
