A--- Allah the Almighty says: {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 to take account}. (AlAnbiya', 47)

Allah the Almighty says: {And the weighing on that day (Day of Resurrection) will be the true (weighing). So as for those whose scale (of good deeds) will be heavy, they will be the successful (by entering Paradise). And as for those whose scale will be light, they are those who will lose their own selves (by entering Hell)

because they denied and rejected Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.)}. (Al-A'raf, 8, 9)

Allah the Almighty says: {So their works are in vain, and on the Day of Resurrection, We shall assign no weight for them}. (Al-Kahf,105)
