It is narrated from Sayyiduna Zubair (may Allah be pleased with him) that when this verse was revealed: «ثُمَّإِنَّكُمْيَوْمَالْقِيَامَةِعِنْدَرَبِّكُمْتَخْتَصِمُونَ»[الزمر : 31] "Then on the Day of Resurrection you will dispute before your Lord," he asked: O Messenger of Allah! Is the disputing meant here the disputing with opponents in this world? The Prophet (peace and blessings be upon him) said: "Yes." Then when this verse was revealed: «ثُمَّلَتُسْأَلُنَّيَوْمَئِذٍعَنِالنَّعِيمِ»[التكاثر : 8] "On that Day you will surely be questioned about the blessings," Sayyiduna Zubair (may Allah be pleased with him) asked: O Messenger of Allah! About which blessings will we be questioned? When all we have is dates and water. The Prophet (peace and blessings be upon him) said: "Beware! The time of blessings is also soon to come."
