There is no torment for souls more severe than ignorance, for it is all foolishness, and that is why it is called the Day of Deception. He means the day of torment of souls. He says, “Oh, woe to me for what I neglected.” And it is the day of heartbreak. He says, “The Day of Revealing: Whoever regrets the thing,” when I uncover it, it is as if he is saying, “Oh, I wish I had regretted this.” The matter is in this world, so I will be aware of my affairs, so he will be deceived in himself, and the deviant will realize on that day everyone, the obedient and the disobedient. The obedient one will say, “I wish I had done my best and fulfilled what was right of my ability and considered the words of my Lord and acted according to them even though He was happy.” And the disobedient one says, “I wish I had not disobeyed my Lord in what He commanded me and forbade me on that day.” Transgression, and this will come in the chapter on the Day of Resurrection, God willing .
