Yusuf Mansur

In 1996 he was involved in the business related to information technology, but his business caused him to become heavily indebted and put him in detention for two months. He repeated this in 1998. During his jail time, he considered that he discovered the wisdom of sadaqah (lit: benevolence, charity). After the release from the prison, he tried to restart a business from scratch by selling ice at Kalideres terminal. He eventually expanded his business to the retail of thermos and carts and then managed to own employees. He considers that his life began to change as he became acquainted with a policeman who introduced him to an NGO. During his work in the NGO, he wrote a book regarding sadaqah and his experience in prison, yearning for his parents.
