Adh-Dhariyat · 51:49Makkah

Everything comes in pairs, so you remember the One.

Pairs point to the One without a pair

Created in pairs
night and day
land and sea
life and death
so that you remember
Allah is Onewithout partners
What the pairs teach
creation is complete alone
only the Creator has no paireverything else needs another

The tafsir lists the pairs: heaven and earth, night and day, sun and moon, land and sea, faith and disbelief, misery and happiness, Paradise and Fire. All of it so that you remember the Creator is One.

Your phone and its charger. Your left hand and your right. Morning coffee and evening tiredness. Everything you own needs a partner to work. The One who made them all needs nothing.

Pairs are just how things happen to be.

Everything needing another reminds me that Allah alone needs no one.

Try this

Notice three pairs around you today and, for each, say Allah is One.

Tafsir Ibn Kathir (shared passage from 51:47)

With Hands We constructed the heaven. Verily, We are able to expand the vastness of space thereof (47)And We have made the earth a Firash; how excellent spreader (thereof) are We (48)And of everything We have created pairs, that you may remember (49)So, flee to Allah. Verily, I am a plain warner to you from Him (50)And set not up any other god along with Allah. Verily, I am a plain warner to you from Him (51)

Proofs of Allah's Oneness abound in the Creation of the Heavens and the Earth

Allah reminds us of the creating of the higher and lower worlds,

وَالسَّمَاءَ بَنَيْنَاهَا

(We constructed the heaven.) meaning, 'We made it as a high roof, protected from falling,'

 بِأَيْدٍ

(with Hands), meaning, with strength, according to 'Abdullah bin 'Abbas, Mujahid, Qatadah, Ath-Thawri and several others,

وَإِنَّا لَمُوسِعُونَ

(Verily, We are able to extend the vastness of space thereof.) means, 'We made it vast and We brought its roof higher without pillars to support it, and thus it is hanging independently.'

وَالْأَرْضَ فَرَشْنَاهَا

(And We have made the earth a Firash), meaning, 'We have made it a resting place for the created,'

 فَنِعْمَ الْمَاهِدُونَ

(how excellent a spreader (thereof) are We!), meaning, 'We spread it for its inhabitants,'

وَمِنْ كُلِّ شَيْءٍ خَلَقْنَا زَوْجَيْنِ

(And of everything We have created pairs,) meaning, all the created are in pairs, the heaven and earth, night and day, sun and moon, land and sea, light and darkness, faith and disbelief, death and life, misery and happiness, Paradise and Fire, in addition to the animals and plants. The statement of Allah the Exalted,

لَعَلَّكُمْ تَذَكَّرُونَ

(that you may remember.) and know that the Creator, Allah, is One without partners,

فَفِرُّوا إِلَى اللَّهِ ۖ 

(So, flee to Allah.) meaning, seek shelter with Him and trust in Him in all of your affairs,

إِنِّي لَكُمْ مِنْهُ نَذِيرٌ مُبِينٌ - وَلَا تَجْعَلُوا مَعَ اللَّهِ إِلَٰهًا آخَرَ ۖ

(Verily, I am a plain warner to you from Him. And set not up any other god along with Allah.) do not associate any partners with Him,

إِنِّي لَكُمْ مِنْهُ نَذِيرٌ مُبِينٌ

(Verily, I am a plain warner to you from Him.)
