Shaykh Dr. Yasir Qadhi discusses verses 96 - 115 of Surah Al Muminun and we get acquainted with the trueness of Judgement Day.
‘Repel, by (means of) what is best, (their) evil. We are most knowing of what they describe. And say, "My Lord, I seek refuge in You from the incitements of the devils, And I seek refuge in You, my Lord , lest they be present with me.(For such is the state of the disbelievers), until, when death comes to one of them, he says, "My Lord, send me back that I might do righteousness in that which I left behind." No! It is only a word he is saying; and behind them is a barrier until the Day they are resurrected.’
At the time of the blowing of the Horn, relationships will cease to exist and one will fail to worry or care for his own. The ones whose scales are heavy with good deeds will emerge victorious and successful. The one whose scales are light will go to Hell where they will live till eternity.
