And (remember) the Day that the enemies of Allah will be gathered to the Fire, so they will be collected there (the first and the last).
Till, when they reach it (Hell-fire), their hearing (ears) and their eyes, and their skins will testify against them as to what they used to do.
And they will say to their skins, “Why do you testify against us?” They will say: “Allah has caused us to speak, as He causes all things to speak, and He created you the first time, and to Him you are made to return.”
Chapter 41 Fuşşilat : Verses 19-21
On the Day of Judgement, the Sinners’ Limbs will testify against Them
(And (remember) the Day that the enemies of Allah will be gathered to the Fire, then they will be driven.) means, remind these idolators of the Day when they will be gathered to the Fire and they will be driven, i.e., the keepers of Hell will gather the first of them with the last of them, as Allah says elsewhere:
(And We shall drive the criminals to Hell, in a thirsty state) (19:86).
(Till, when they reach it,) means, when they stand at its edge,
(their hearing (ears) and their eyes and their skins will testify against them as to what they used to do.) means, all their deeds, earlier and later; not a single letter will be concealed.
(And they will say to their skins, “Why do you testify against us”) they will blame their limbs and their skins when they testify against them, at which point their limbs will answer:
(They will say: “Allah has caused us to speak — as He causes all things to speak, and He created you the first time,) means, and He cannot be opposed or resisted, and to Him you will return. Al-Hafiz Abu Bakr Al-Bazzar narrated that Anas bin Malik, may Allah be pleased with him, said, “The Messenger of Allah laughed and smiled one day, and said:
(Will you not ask about why I laughed)” They said, “O Messenger of Allah, why did you laugh” He said:
(I was amazed at how a servant will dispute with his Lord on the Day of Resurrection. He will say, “My Lord, did You not promise me that you would not treat me unjustly” Allah will say, “Yes.” The man will say, “I will not accept any witness against me except from myself.” Allah will say, “Is it not sufficient that I and the angels, the noble scribes, are witnesses” These words will be repeated several times, then a seal will be placed over his mouth and his organs (or limbs) will speak about what he used to do. Then he will say, “Away with you! It was only for your sake that I was arguing!”)” It was recorded by him and Ibn Abi Hatim. It was also recorded by Muslim and An-Nasa’i. Ibn Abi Hatim recorded that Abu Burdah said that Abu Musa said, “The disbeliever or the hypocrite will be called to account and his Lord will show him his deeds, but he will deny them and say, `O Lord, by Your glory, this angel has written about me something that I did not do.’ The angel will say to him, `Did you not do such and such on such and such a day in such and such a place’ He will say, `No, by Your glory O Lord, I did not do it.’ When he does that, a seal will be placed over his mouth.” Al-Ash`ari, may Allah be pleased with him, said, “I think that the first part of his body to speak will be his right thigh.”
