The verses call the reader to reflect (tadhakkur, 51:49) on the paired nature of creation, and Ya-Sin opens with 'Pure/Glory is He who created all the pairs' (36:36) - directing the heart from observing this universal duality to declaring Allah transcendent above every imperfection His creation shows. Q1Q2

The Prophet taught 'Allah is Witr (One) and loves the witr,' pairing this declaration with the enumeration of His ninety-nine names, and he himself prayed and commanded the odd-numbered Witr prayer - tying an act of worship to the theological truth of Allah's oneness. H4H1

Al-Sindi explains Allah's oneness in three respects - indivisible in essence, unlike anything in attributes, unaided by any partner in action - while Ibn Hajar reports al-Qurtubi's view that the hadith calls believers to tawhid: that Allah alone, unlike everything paired that He creates, has no like or partner. C1C6

The Qur'an's repeated notice that everything else is created in pairs is meant to turn reflection toward the one exception - Allah - who alone is single, matchless and worthy of worship without partner. Q1T1C6

Maarif-ul-Quran explains that a 'zawj' (pair) is not only a male-female couple but any two things of a matching kind, so 'pairs' also covers contrasting qualities like heat and cold, or land and water. T2

Adh-Dhariyat 51:49 lists heaven and earth, sun and moon, mountain and plain, summer and winter, sweet and bitter, light and darkness as pairs so 'that you may heed'; Ar-Ra'd 13:3 calls such signs food for 'a people who reflect'. Q1T1Q3

Al-Jalalayn says recognising the Creator of all these pairs leads to realising He Himself is Singular, and so worthy of worship alone; Maarif-ul-Quran notes the Qur'an even points to pairs 'they do not know', hinting at pairing in minerals and other creation not yet discovered. T1T2

Every contrasting pair observed in the world - from night and day to sweet and bitter - is meant to point the observer back to the one, matchless Creator who has no pair.

A zawj (pair) is one of two matching things of the same kind — a couple or counterpart of the other — extended by the mufassirun beyond male and female to any two contrasting things, such as heat and cold or land and water. T2

The reader is called to see paired creation as a sign pointing beyond itself: general reflection is the purpose stated for pairs at large, while for spouses specifically the Qur'an names tranquility, love and mercy as the fruit of that pairing. Q1Q4Q5

The Prophet taught that Allah alone is 'Witr,' loving odd numbers, and instructed 'the people of the Qur'an' to pray Witr — locating Allah outside the pairing that characterises everything He creates. H1H2

Al-Jalalayn says the purpose of pairs like male/female, heaven/earth and sun/moon is that one might 'realise that the Creator of pairs is Himself Singular.' Mufti Muhammad Shafi (Maarif-ul-Quran) adds that the specific wisdom of the spousal pair is tranquility, achieved only through mutual recognition of each other's rights. Al-Sindi explains that Allah's being Witr means one in essence, attributes and acts — unlike any paired thing. T1T4C2

Fujur means open transgression and taqwa means piety/God-consciousness; the Qur'an says both were 'inspired' (cast) into the soul, and separately that man was shown 'the two ways' — framing moral good and evil as a paired capacity built into human nature, distinct from the physical pairs (day/night, sun/moon) discussed elsewhere. Q2T2Q3

The Qur'an calls the reader to recognise this given duality and actively choose gratitude and piety over ingratitude and transgression, since Allah has 'shown him the way, whether he be grateful or ungrateful' — the choice, and its consequence, is the reader's own. Q4

The Prophet taught that truthfulness leads step by step to righteousness and Paradise while falsehood leads step by step to wickedness (fujur) and the Fire, and that calling others toward guidance or misguidance earns a matching share of reward or sin — urging the reader to embody and spread the good pole of this pair. H7H12

Mufti Muhammad Shafi explains that this pairing of fujur and taqwa in the soul is proof that man is not a creature of pure coercion: Allah gave him conscience and genuine free will to do good or commit sin, and reward or punishment follows from which he chooses. T2
