Sūrah Al-Muʾminūn The Believers
سورة المؤمنون
Al-Qurṭubī extracts from Al-Muʾminūn's opening description of successful believers (23:1–11) a comprehensive list of obligatory and recommended worship characteristics mapping the legal status of each (farḍ, sunnah, mustaḥabb) and uses 23:5–7 on sexual morality to derive the four-school positions on the conditions for valid marriage.
Surah Overview
Key Themes from Al-Qurṭubī
Al-Qurṭubī opens Al-Muʾminūn with a systematic legal analysis of the eight qualities of the successful believers (23:1–11): (1) khushūʿ (humility) in prayer obligatory, without which prayer is deficient; (2) avoidance of laghw (vain speech) recommended avoidance, though some classify it as obligatory; (3) performance of zakāh obligatory (farḍ ʿayn); (4) guarding private parts obligatory; (5) faithfulness to trusts obligatory; (6) honouring pledges obligatory; (7) guarding the prayers obligatory. He notes that six of the eight qualities are obligatory (farḍ), establishing that the profile of the successful believer is primarily a legal-obligation profile, not merely a virtue profile.
On khushūʿ in prayer (23:2), al-Qurṭubī addresses whether khushūʿ (presence of heart) is a legal condition (sharṭ) of valid prayer or a recommended addition. He maps the debate: most scholars hold it is not a legal validity condition (prayer is valid without khushūʿ as long as the external conditions are met) but it is a moral obligation prayer without khushūʿ is valid in law but deficient in religion. The famous saying "Woe to the praying ones who are heedless of their prayers" (107:4–5) refers to those lacking khushūʿ, not to those missing external conditions.
- Eight qualities legal status: Al-Qurṭubī's systematic mapping of the eight believer-qualities to their legal status (six farḍ, two recommended) is a characteristic fiqh-extraction methodology applied to a theological passage.
- Khushūʿ debate: Al-Qurṭubī documents the khushūʿ-as-condition vs. khushūʿ-as-obligation debate concluding it is a moral obligation not a validity condition, with prayer valid but spiritually deficient without it.
- Two-category exhaustion: The exception structure of 23:6 is read as an exhaustive restriction mutʿah and any other third category are excluded by the "fa-man ibtaghā warāʾa dhālika" transgression clause.
- Mutʿah four-school prohibition: Al-Qurṭubī documents the complete four-school prohibition of mutʿah marriage one of the clearest inter-school consensus positions in personal status law.
- Success profile as legal: Al-Qurṭubī reads the "successful believers" profile as primarily a legal-obligation profile the Quran describes success through legally obligatory acts, not merely supererogatory virtues.
