Musharraf announced the donation following the mass devastation caused by the floods, claimed the All Pakistan Muslim League (APML) chief coordinator.
He also raised charges against the federal and provincial governments of not providing enough relief to the affected people and millions of people were still in urgent need of food, shelter and medical supplies.
Over 1,600 people had been killed and 15 million affected as raging floodwater continue to wreak havoc in the country.
In addition to causing major human loses, it has destroyed hundreds of thousands of homes, washed away crops and livestock.
Relief and rescue work has been hit badly by continuous rains, particularly in the north western region.
The United Nations says that Pakistan will need billions of dollars to recover from the deluge, which is being described as the worst in the last 80 years.
