Al-Mas'udi said this quote

The sciences were financially supported, honoured everywhere, universally pursued; they were like tall edifices supported by strong foundations. Then the Christian religion appeared in Byzantium and the centres of learning were eliminated, their vestiges effaced and the edifice of Greek learning was obliterated. Everything the ancient Greeks had brought to light vanished, and the discoveries of the ancients were altered out of recognition.

~ Al-Mas'udi

He who has never left his hearth and has confined his researches to the narrow field of the history of his own country cannot be compared to the courageous traveller who has worn out his life in journeys of exploration to distant parts and each day has faced danger in order to persevere in excavating the mines of learning and in snatching precious fragments of the past from oblivion.

It was at this time that backgammon was invented and began to be popular. It is a kind of paradigm of how wealth is acquired, which in this world is not the reward of intelligence or ability, just as luck is not a product of skill... If luck favours the player, he gets what he wants; if it doesn't, a skilled and prudent man cannot win that which fortune only bestows on whom it likes. It is thus that the good things of this world are apportioned by chance.

~ Al-Mas'udi

When a man dies, his wife is burned alive with him, but if the wife dies before her husband, the man does not suffer the same fate. If a man dies before marriage, he is given a posthumous wife. The women passionately want to be burned because they believe they will enter paradise.
