Jami` at-Tirmidhi Book 47, Hadith 408
“When the following was revealed: Then on that Day, you shall be asked about the delights!’ Az-Zubair said: ‘O Messenger of Allah! Which are the delights that we will be asked about, when they (delights) are but the two black things: dates and water?’ He said: ‘But it is what shall come.’”
“We were still in doubt concerning the torment of the grave, until ‘the mutual rivalry diverts you” was revealed’.”
“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.’”
