means, remind these idolaters 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:

{Till, when they reach it,} means, when they stand at its edge,

means, all their deeds, earlier and later; not a single letter will be concealed.

they will blame their limbs and their skins when they testify against them, at which point their limbs will answer:

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."

Allah's saying:

means, their organs and skins will say to them, when they blame them for testifying against them, 'you did not hide from us what you used to do, on the contrary, you openly committed disbelief and sin, and you claimed that you did not care, because you did not believe that Allah knew about all your deeds.' Allah says:

meaning, 'this evil thought, i.e., your belief that Allah did not know much of what you were doing, is what has caused you to be doomed and has made your losers before your Lord.'

means, 'in the place of Resurrection, you have lost your own selves and your families.'

Imam Ahmad recorded that 'Abdullah, may Allah be pleased with him, said, "I was hiding beneath the covering of the Ka'bah, and three men came along - a man from the Quraysh and two of his brothers-in-law from Thaqif, or a man from Thaqif and two of his brothers-in-law from the Quraysh. Their bellies were very fat, and did not have much understanding. They said some words I could not hear, then one of them said, 'Do you think that Allah can hear what we are saying now?'
