The above description of the Arab writer indicates that the Vaishyas did the work of the Sudars and the Sudar did the work of the Vishyas. It appears that the caste system was slowly and gradually breaking in a nice manner. The Brahmans started marrying kashatriya girls and the vaishyas performed the work of the sudras as well.
The Muslim attacks had begun during this period and many Hindus of the conquered states had been becoming the followers of Islam. It also appears that the Hindu society had allowed the purification of such Hindus. Smriti Ghandrayana Vrat, 'Biladuri' and the writings of Aluberni and other Muslim writers also confirm this fact.
Some references of the inter caste marriage have also been found. The prominent Sanskrit scholar Rajasekhar had married Kshatriya girl named Avanti Sundari. Kings and the rich classes practiced polygamy. However, usually men had only one wife. It can also be known from some reference where on the death of their husbands, women had burnt themselves along with their husbands. Thus sati pratha was there though it was not very much prevalent.
There was no purdah system among the women of the royal families. According to Rajasekhar women learnt music, dancing and paintings. Women were very much fond of ornaments and also used oils and cosmetics. People of the rich families used to wear very thin clothes. The Arab writer Sulaman has written that in this period, silk used to be so thin and delicate that clothes made of it could pass through a ring.
