The cricketer's son, who is studying in England, had been engaged to Ibrahim's daughter in January this year, an event that was kept a quiet affair.
"We expect the actual ceremony to be a hush-hush one too, with not many guests being invited. We also know for sure that Dawood will not be attending," the sources, speaking strictly on condition of anonymity, said.When news of the engagement surfaced earlier this year, Miandad had reacted angrily, saying he would make no comments on the matter.
At that time he was reported to have said: "I don't understand why people want to interfere in our personal and family life. I don't interfere in anybody else's personal life and we expect them to respect our privacy also."
This time around, Miandad was more composed. When contacted in Lahore on Thursday, Miandad did not deny that the marriage was on the cards. "I will let you know when the wedding takes place. It will not be a secret so let us leave it at that," Miandad said.
The former cricketer is the son-in-law of a leading business family of Pakistan in whose businesses Dawood is believed to have invested heavily, say intelligence sources.
Dawood, who rose rapidly through the ranks of the Mumbai underworld, escaped to Karachi after allegedly engineering the Mumbai terror blasts in 1993 that took more than 300 lives.
Indian authorities have been pursuing him ever since and have even given his name to Pakistan for extradition, but Pakistani authorities have consistently denied any knowledge of his whereabouts.
He also managed to smuggle his family, comprising his wife, four daughters and a son, as well as certain close associates and their families out of Mumbai. One daughter, 12, subsequently died of malaria and is buried in Pakistan.
The sources also indicated that ever since Dawood got involved in match-fixing over a decade ago, many Pakistan cricket players were on his rolls. Miandad, in particular, was considered close to him.
According to these sources, Dawood has not visited Dubai for some time now, especially after the 9/11 attacks in the US. Dubai was earlier the nerve centre of his illegal operations.
