People like us living in far away places from Pakistan like USA and Australia face this situation quite often and decision by Naseem Shah to stay in Australia does make sense to us.
At the time of death in family in Pakistan, it almost impossible for anyone living in USA or Australia to be in Pakistan to attend the funeral, because as per Islamic culture, burial is conducted within 24 hours, most of the time. For this very reason, people not always leave everything and take the next flight to Pakistan but take their time, take care of their most urgent matters and only then go to Pakistan to share the grief with family. Many leave weeks or months later.
Naseem , would not have attended his mother funeral, unfortunately. Considering this , I'm sure PCB would have given him option of staying in Australia and I'm sure after discussing with his family , he decided to stay, which is understandable.
