* On the Day of Resurrection

(Then, when the Trumpet is blown, there will be no kinship among them that Day, nor will they ask of one another. Then, those whose scales (of good deeds) are heavy, they are the successful. And those whose scales (of good deeds) are light, they are those who lose themselves, in Hell will they abide)﴿ 23:101-103
As for what will be placed on the Balance on the Day of Resurrection, it has been said that the deeds will be placed on it, even though they are not material objects. Allah will give these deeds physical weight on the Day of Resurrection.

Al-Baghawi said that this was reported from Ibn `Abbas. It is recorded in the Sahih that Al-Baqarah (chapter 2) and Al `Imran (chapter 3) will come on the Day of Resurrection in the shape of two clouds, or two objects that provide shade, or two lined groups of birds.

It is also recorded in the Sahih that the Qur'an will come to its companion (who used to recite and preserve it) in the shape of a pale-faced young man. He will ask (the young man), "Who are you'' He will reply, "I am the Qur'an, who made you stay up sleeplessly at night and caused you thirst in the day. ''
