He bought a rickshaw in 1982 and started his business life. He used to get 7 rupees per day from rickshaw. He bought another rickshaw with the profit. He used to get 12 rupees a day from two rickshaws. After 2 years, he joined the partnership business with the then Zeba Jewelery in 1984 with only 4,000 rupees. With an indomitable desire to do something for himself, he saved some more money and joined Alangkar Niketan, the big shop of that time. At that time the capital was only 20 thousand rupees. This is how he spent year 2. In 1986, with a capital of only 1 lakh rupees, he bought a shop in Baitul Mukarram to run his own business. Capital is low but I didn't know how to say so. At this time the relatives extended their hand of cooperation. He received about 100 tons of gold from family members to decorate the shop. Conditions None of these jewelry can be sold. You can arrange the shop on the condition of attracting customers. The diameter didn't start and look back.

Any order, big or small, was taken seriously. He used to walk from Baitul Mukarram to Shyamoli to deliver a little nose flower on time. It would cost more to get in the vehicle, so he would go on foot. Not only did he supply orders on time but he also kept the quality right. And so day by day only the customer is running away.

The war of liberation started in 1971. He could not take direct part in the great liberation war. But he kept track of the freedom fighters regularly. He provided medicine and money as needed. Once the news came that the freedom fighters were injured in the attack of Pakistanis. Severe hemorrhagic condition. The situation is worse. It takes a lot of money to buy medicine for treatment. He left the shop and went down. Dr. Together with Alim Chowdhury, he collected money from the market of Baitul Mukarram and came to treat the wounded freedom fighters. After receiving this news from somewhere, the Pakistanis filled the truck and left the next day. Who is Kazi Sirajul Islam? Sirajul Islam wanted to know in Urdu. Sirajul Islam said I am. The Pakistanis did not trust a young man with a thin body as the owner of the shop. Released him. Seeing that the level of persecution of Hindus was increasing day by day, most of the Hindu gold traders of that time migrated to India. The business of selling gold is kind of closed.

The country became independent. Kazi Sirajul Islam started a new gold business. He did a flat business in an independent country. Referring to that time as the best time of business, he said that he would take all orders, big and small, seriously. I did not skimp on customer service. The business did not have to look back to be able to deliver on time while maintaining quality. Today Amin Jewelers has 5 state-of-the-art showrooms in Dhaka. Amin Jewelers has been holding people's trust for more than 5 decades.
