Who is Kabir Durrani from A Suitable Boy: A Novel and what is their importance?

Kabir is the epitome of the "unsuitable boy" in this story of Hindu marriage customs. His main failing is the unfortunate circumstance of having been born a Muslim. Kabir is not overly religious and is atypical of the Muslim male looking for a plurality of wives. He falls in love with Lata almost from first sight and pursues her relentlessly.
