The Qur’anic expression aqqadtum al-ayman helps determine the class of oath relevant to this particular legal consequence. The literal sense of “binding” refers to establishing an oath, not simply forming a passing intention.
«ولكن يؤاخذكم بما عقدتم الأيمان»
But He takes you to account for the oaths you have bound firmly.
The textbook therefore treats this wording in connection with an effective, binding oath (yamin mun‘aqidah) rather than automatically assimilating the deliberately false oath (yamin ghamus). This is a specific juristic reading that preserves the operative sense of “binding.”
