Does taking an oath that 'we shall not separate' result in breaking the oath if the subject of the oath flees?
General Chapter
Al-Mughni
Book of Expiations
Primary text
The oath-taker breaks their oath (breaks *yamin*) if the entity upon which the oath was sworn flees from the oath-taker, because the oath implies that no separation should occur between them in any manner, and separation has indeed occurred through the fleeing. This is the ruling in this situation.
Supporting text
If the separation occurs because both parties were compelled or coerced (*ukriha*) into separation, the oath-taker does not break the oath, except according to the opinion that coercion is not considered a valid excuse (*udhr*).
