Musannaf Ibn Abi Shaybah

Hazrat Husain narrates about Ibrahim Taimi, he says that among his sayings was this: What greater regret can a man have than that his slave, whom Allah made his slave in this world, attains a higher rank with Allah on the Day of Judgment? What greater regret can a man have than that Allah gave him wealth in this world, and he made someone else the heir of that wealth, then that heir obeys Allah with that wealth? Thus, the sin of the wealth is upon the owner, and its reward is for another? And what greater regret can a man have than to see a servant who was blind in this world, that Allah opened his sight and this one became blind? Then he (may Allah be pleased with him) said: The people before you used to flee from the world while the world turned towards them. And whatever status they attained, they attained it. But you people pursue the world while the world has turned away from you, and the punishment that is to befall you will befall you. So compare your situation with theirs.
