It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Two Muslims met at the gate of Paradise; in the world, one of them was wealthy and the other was poor. The poor one entered Paradise, and the wealthy one was held back, and he was kept waiting as long as Allah willed. Then he too entered Paradise. There he met that poor man. The poor man asked him, 'Brother! What caused you to be so late? By Allah! You were so delayed that I began to worry.' He replied, 'Brother! After you, I was held back in such a way that it was an extremely difficult and unpleasant stage, and before reaching you, so much sweat poured from my body that if there had been a thousand hungry and thirsty camels, and they had drunk that sweat instead of water, they would have been satisfied.'"
