Translation of the verse 47 from Surah Al-Anbiya’ : Number of verses 112 - - page 326 - Part 17.
And We shall set up balances of justice on the Day of Resurrection, then none will be dealt with unjustly in anything. And if there be the weight of a mustard seed, We will bring it. And Sufficient are We as Reckoners.
And We place the scales of justice for the Day of Resurrection, so no soul will be treated unjustly at all. And if there is [even] the weight of a mustard seed, We will bring it forth. And sufficient are We as accountant.
(21:47) On the Day of Resurrection, We will set up just and accurate balances so that no one will be wronged in the least in anyway; even if it be an act equal in weight to a grain of mustard seed, We will bring it forth (to be weighed) and We suffice for reckoning. *48
*48) See also vv. 8-9 and E.N.'s 8-9 of Al-A'araf (Vll). It is difficult for us to understand the exact nature of the "Balance". Anyhow it is clear that the "Balance" will weigh accurately all the human moral deeds instead of material things, and will help judge whether a man is virtuous or wicked and how much. The Qur'an has used this word to make mankind understand that every deed, good or bad, will be weighed and judged according to merit.
