 Zarobai is the continuation of the historical village Munara which was once existed at the coast of Indus (Abaseen river) and then destroyed two times in Indus floods.After that crucial incident the people of that destroyed village were brought together at Zarobai derai and later it was named just Zarobai.When the partition of the whole territory belonging to the Pashtoons was taking place among-st their tribes by Shiekh Milli's partition rule, our ancestors were given their part/portion at Munara but it was a small village and their share was much greater which was impossible to be given here so they got their remaining portion at Trapakai (now included in Tarbela Dam) and Pajman.
