Al-A'raaf 7:8

The weighing [of deeds] on that Day will be true and just. Those whose scales [of good deeds] are heavy, it is they who will be successful.

And the weighing [of deeds] that Day will be the truth. So those whose scales are heavy - it is they who will be the successful.

8. And the weighing on that day (Day of Resurrection) will be the true (weighing)[1]. So as for those whose scale (of good deeds) will be heavy, they will be the successful (by entering Paradise).

[1] (V.7:8) The Statement of Allâh عز وجل:
"And We shall set up balances of justice on the Day of Resurrection." (V.21:47).
The deeds and the statement of Adam’s offspring will be weighed.
Narrated Abu Hurairah رضي الله عنه: The Prophet صلى الله عليه وسلم said, (There are) two words (expressions or sayings) which are dear to the Most Gracious (Allâh) and very easy for the tongue to say, but very heavy in the balance. They are: سبحان الله وبحمده - سبحان الله العظيم
Subhân Allâhi-wa bihamdihi - Subhân Allâhil-‘Azîm’ " (Sahih Al-Bukhârî, Vol. 9. hadîth No.652).
‘Glorified be Allâh and praised be He’ - ‘Glorified be Allâh, the Most Great.’ (or I deem Allâh above all those unsuitable things ascribed to Him, and free Him from resembling anything whatsoever, and I glorify His Praises! I deem Allâh, the Most Great above all those unsuitable things ascribed to Him and free Him from resembling anything whatsoever).

The weighing on that day is the true (weighing). As for those whose scale is heavy, they are the successful.
