الله الذي أنزل الكتاب بالحق

It is Allah Who has sent down the Book in truth, referring to all the Books which were revealed from Him to His Prophets.

والميزان

and the Balance. means, justice and fairness. This was the view of Mujahid and Qatadah. This is like the Ayat:

لقد أرسلنا رسلنا بالبينت وأنزلنا معهم الكتب والميزان ليقوم الناس بالقسط

Indeed We have sent Our Messengers with clear proofs, and revealed with them the Scripture and the Balance that mankind may keep up justice. (57:25)

والسماء رفعها ووضع الميزان

أﻻ تطغوا فى الميزان

وأقيموا الوزن بالقسط وﻻ تخسروا الميزان

And the heaven He has raised high, and He has set up the Balance. In order that you may not transgress (due) balance. And observe the weight with equity and do not make the balance deficient. (55:7-9)

وما يدريك لعل الساعة قريب

And what can make you know that perhaps the Hour is close at hand? This is encouragement (to strive) for its sake, a terrifying warning, and advice to think little of this world
