In the first concession, severe coercion grants restricted relief while the underlying prohibition remains; the textbook praises steadfast endurance. In the second, something ordinarily forbidden becomes permissible as necessary to preserve life, and refusing the now-permitted lifesaving means can be blameworthy.
The key is not simply whether a case is “difficult,” but what happens to the underlying rule, what condition justifies the concession, and what consequence the text attaches to that condition.
The textbook closes with “تم الكتاب والحمد لله” (“The book is complete, and praise belongs to God”). Across the course, interpretation of wording, Sunnah, consensus and analogy has led to the final understanding of legal grades and their carefully limited exceptions.
