Sūrah 89 · Āyāt 1–5

The sūra opens with a cascade of oaths — "By the dawn, and ten nights, and the even and the odd, and the night when it departs" — capped by a question that is really an affirmation: "is there in that an oath for one possessing reason?" The response of the oath is left unspoken, and the present sources read that suppression as deliberate.

What the oaths name. On the plain sense the sources largely converge. Al-Mīzān (Ṭabāṭabāʾī) takes "the dawn" as the absolute daybreak, "the even and the odd" as number itself — a reminder of the blessing of measure — and "the night when it departs" as the generic end of night, the whole cascade pointing to God's ordering power. Majmaʿ al-Bayān (Ṭabarsī) and al-Tibyān (Ṭūsī) catalogue the classical opinions: the dawn of Dhū al-Ḥijja; the ten nights as its first ten (the relied-upon view, per Ṭūsī); the even/odd as the Day of Sacrifice and the Day of ʿArafa, or as creation (even) and the Creator (odd). Ṭūsī supplies the lexical precision the others assume — distinguishing the "false dawn" that rises like a wolf's tail (no ruling in the Law) from the "true dawn" at which the fast begins — and both he and Ṭabarsī gloss ḥijr as the intellect that "restrains" (yaḥjuru) one from foul deeds.

The breadth of meaning. The Enlightening Commentary (Imani) frames these as "five awakening oaths" and, like al-Mīzān, refuses to narrow them: the dawn is "any light that glitters in the dark," and the image is extended to the dawn of Islam, the rising of Imam Mahdi, and the rising of Ḥusayn at Karbalāʾ — while insisting the verse's apparent sense remains simply "the break of dawn."

The Imāmī reading. The Arabic Shīʿī sources add taʾwīl. Tafsīr al-Qummī preserves both a fiqhī gloss (shafʿ/witr as the two- and one-rakʿa night prayers) and an esoteric one (even = al-Ḥasan and al-Ḥusayn, odd = the Commander of the Faithful). Al-Burhān (Baḥrānī) gathers the fullest chain, from al-Ṣādiq: "the dawn is al-Qāʾim; the ten nights are the Imams from [Imam] al-Ḥasan to [Imam] al-Ḥasan al-ʿAskarī; the even is Amīr al-Muʾminīn and Fāṭima; the odd is God; and the night when it departs is the rule of Ḥabtar, running on until the rule of al-Qāʾim." (Ḥabtar — "the fox" — is a coded taqiyya epithet; these are recorded as attributed reports, not the verse's plain sense.) Tellingly, even Baḥrānī cites Ṭabarsī's pilgrimage reading alongside, holding plain sense and taʾwīl together.

Convergence. All present sources agree the unspoken answer of the oath is the certainty of recompense. al-Mīzān states it outright: the elided response is the punishment of the tyrants and the reward of the serene souls, and the eliding "is more impactful and emphatic in warning and glad-tidings." The oaths are not riddles but a summons addressed to "one possessing reason".
