Qawaa‘id al-Fiqhiyyah al-Asliyyah

The maxims that apply to business transaction will …. duhh … most likely be the ones related to muamalat (dealings with others).

Obviously. we need to cover the the normative legal maxims (al-qawa‘id al-fiqhiyyah al-asliyyah) because, as noted by Kamali, this set of basic maxims cover the entire fiqh:

• “Harm must be eliminated” (Ad-dararu yuzal)
• “Acts are judged by the intention behind them” (Al-umuru bi-maqasidiha)
• “Certainty is not overruled by doubt” (Al-yaqinu la yazulu bish-shakk)
• “Hardship begets facility” (Al-mashaqqatu tujlab at-taysir)
• “Custom is the basis of judgement” (Al-‘addatu muhakkamatun)

…. I definitely need to research more on this.
