Mohammad Ruhul Amin married and had three daughters (one called Noor Nagher) and one son, Shawkat Ali. All four children grew up and got married. Sadly, Shawkat has struggled to maintain his family financially and lives in poverty. He struggles to make a living and works as a day labourer and van-puller.
Shawkat's three sisters take three-fourths of the government assistance meant for the family and so, he often passes hard time with his scanty income.
