I found this information written in a board inside the palace with the Title: Glory belongs to God:
A munificent ruler, Afzal ud Daula’s generosity spread beyond the boundaries of his state and across the seas to the holy cities of Mecca and Medina. At Mecca and Medina, the Nizam procured and built houses and travel inns known as Rubbaths to provide free accommodation to pilgrims from the Hyderabad Dominion. Rubbaths were built in the name of Afzal ud Daula, his mother Dilawarunissa Begum, his wife Hussain Bibi Saheb and in the names of other ladies of the Royal family. In Mecca alone, there used to be five Rubbaths, seventeen shops, three houses and seven godowns. In Medina, there were two Rubbaths, six shops and a house.
Under the Aegis of the Awkaf committee of the HEH the Niza, some of these Rubbaths continued to provide free accommodation to thousands of citizens of the Old Hyderabad dominion who visited the two holy cities every year.
The contributions of the Nizams to the holy cities extended beyond providing for the needs of pilgrims from Hyderabad.
HEH Mir Osman Ali Khan, Nizam VII further contributed towards improving facilities in Mecca and Medina. In 1933, he sent generators for the electrification of the Kabbah and was the first to help electrify the city of Medina. He also assisted the government of Saudi Arabia to lay roads, so as to enable pilgrims to perform the Haj.
Charity without ostentation has been the hallmark of this dynasty and continues quietly even today.
