Why did Suraiya did not objected wid her sister's murgawala pati?

If Suraiya hates poor people so much such as Shazia n Aaliya's family why she did not objected her own sister Zarina marrying a murgawala Rehman? I watched a little bit of d show here n there but after Zain meeting Aaliya in Hyderabad I watched regularly. She even called Rehman to Mumbai to reunite him wid her sister. I am sure Rehman is poorer than Ghulam.

Well as far as i remember in the beginning suraiya never really know who rehman chacha was (remember when suraiya asked if zaro knows rehman..after he calls her "zaro" in their first meeting?) that's why i feel she never really know to whom or how did zaro get married..all she knew was that her sister had a broken marriage..but when she did ..she was already a changed person .. so that's might be the reason why she never pick at her sister for being murgawala's biwi
