Commentary on Tafsir al-Jalalayn: ((Until when they came to it)) the word "ma" is superfluous ((their hearing, their sight, and their skins testified against them as to what they used to do)).

to the end of it. The author said: "superfluous", meaning the word is superfluous, because it occurred after , and whenever occurs after , it is superfluous. And you should memorize this verse:
O seeker, take a benefit: after is superfluous.
.... He says: "excess" meaning they reached it before entering it. These limbs will testify against them so that they enter while being certain that they were treated with justice and fairness. Does their hearing testify to what they heard of idle talk and forbidden speech, or does the hearing testify to all their actions? It carries two possibilities: either the meaning is that their hearing testified to what they heard of falsehood, their sight to what they witnessed of falsehood, and their skin to what they touched of falsehood; or that these limbs testify to every action they performed. Both are possible, and the second is greater: that the hearing testifies to what occurred through it, to what occurred through the sight, and to what occurred through touch. This is greater than if it testified only to what occurred through it. Is this after denial, or for verification and emphasis? The verse contains nothing indicating that, but it was said that these limbs, along with their hands and feet as in another verse, that this only occurs after their denial of having associated partners with Allah, as He the Exalted said: And His saying: "by what you touched" is more general than the testimony of the hearing and sight, because it includes the hand, the foot, the sense of smell, and so on, all of which are through contact.
