Ayah 4
wa Lam yakun lahu kufuwwan ahad (And Nor was there to Him any equivalent.)
Kufuw - your partner, it can also be your equal opposition in battle. Someone who is equal to you in rank, compatible with you, similar in your level. This is why it is used for marriage partners.
So Allah is saying He had no Kufuw - equal in His Ahad (Uniqueness).
In Normal Arabic Grammar Sentence; -
wa lam ya kun ahadun kufuwwan lahu (and there is not any equivalent to Him).
This is the grammatically normal sequence.
ahad is at the end
Lahu is in the beginning.
Kufuw is in the middle.
The normal grammatical sentence would have placed Allah in the end. But Allah switches the normal phrase, and instead mentions Himself first.
Lahu - for Him [Allah], this is Taqdeem - placed earlier in the sentence, showing specificness. There is none La Hu (For Him) an equal competitor (kufuw) ahad - anyOne.
Ahad is awwal - the One for whom there is no 2nd. And the One who is First. He has no counterpart, there is none higher than Him. Yet everythingof the creation has an equal competitor or one better than him, but there is none competing with Allah in His Uniqueness.
Benefits of this Surah:
The first part of the surah shows Allah's Oneness.
The second part of surah show's Allah's grace and Mercy upon us - because He turns to us to help us.
The 3rd ayah shows that Allah is free from weakness. Because having children can be a sign of weakness because you want your name to live on. (Even if you don't feel this now, you might at the age of 40 because you wonder what you have left behind in this world).
The honoring of humans is them having children, because they will require them for strength in old age. The honoring of Allah is that He has no children, because He is always free of need.
This surah in conclusion is probably the most important surah for our children to internalise. What does it mean that He is; Ahad, as-Samad? Lam yaLid, wa lam yuWlad, wa lam ya kun Lahu kufuwan Ahad.
We learn that Allah helps us in all times because He has no competitor (kufuw) in preventing Him from helping us and answering our prayers.
Surah an-Najaat - it Rescues you from ; sadness and hardships, and hellfire, and this is why the companions of Allah's Messenger loved it so much.
