In a hypothetical situation of acute necessity or compulsion, the first task is not recalling the label rukhsah; it is establishing whether the required recognized excuse truly exists. The book's treatment of concessions is attentive to differing situations and conditions.
Rather than issuing a sweeping ruling from one short description, distinguish the type of hardship, its seriousness, the act in question, and the limits of any allowance. Specific real-life determinations require appropriate juristic investigation.
