الْمُخْتَصَرَ الْمُسَمَّى بِالْعَقَائِدِ
The concise treatise named al-ʿAqāʾid.
Ikhtiṣār is the disciplined presentation of essential content without unnecessary length. It does not mean that the subject is easy or that the statements are mere headings. A brief formulation may contain qualifications that become clear only through definitions, arguments and responses to objections.
For example, the word 'one' in a discussion of divine unity leads to important questions concerning divinity, attributes and the distinction between Creator and creation. Sound compression preserves meaning; commentary unfolds it.
Al-ʿAqāʾid focuses on foundational convictions; applied legal details belong to their own discussion, and every subsidiary legal disagreement is not automatically a doctrinal dispute.
