Jami` at-Tirmidhi 3357

Abu Hurairah said:“When this Ayah was revealed: ‘Then on that Day, you shall be asked about the delights!’ the people said: ‘O Messenger of Allah! About which delights shall we be asked? For they are only the two black things, while the enemy is present and our swords are (at the ready) upon our shoulders?” He said: ‘But it is what shall come.’”
