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

An agile, well-trained, brave elephant, ridden by a good mahout, its trunk armed with the kind of sabre known as a qartal and covered with chain mail, while the rest of its body is protected by sheets of bark and iron, surrounded by 500 men to defend it and protect it to the rear, can fight against 6000 men on horseback.

~ 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.

~ Al-Mas'udi

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.
