Jami` at-Tirmidhi 3356

Abdullah bin Az-Zubair bin Al-Awwam narrated from his father who said:“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.’”
