He created a record when he responded to the call of Prime Minister Lal Bahadur Shastri in 1965. The PM visited Hyderabad and requested the Nizam to contribute generously to the National Defence Fund, set up in the wake of the Indo-Chinese skirmish. Without a second thought, Mir Osman Ali announced that he would contribute FIVE TONS of gold to augment the war fund.

Now here is another shade of the Nizam..
He knitted his own socks, wore the same patched clothes for months and cadged cigarettes from his guests. Women were his real weakness. His collection of beautiful concubines lived happily, it is said, in strict purdah, kept in complete isolation from all men - except the Nizam.(He sure was colorful...lol)

He was minted yet miserly, and left a family feuding over his fortune.

Saari Zindagi Lagadi tune maal kamaane mei , Ae Insaan!
Magar tu ye bhool gaya, Na Kafan mei Jeb hote hai na Qabar mei Almaari..
