The caliph who introduced stipend for teachers was

The caliph who introduced stipend for teachers was 'Umar. He was one of the early leaders of the Islamic community after the death of the Prophet Muhammad and is known for his wise and just rule. One of his important contributions was to provide financial support for teachers in order to encourage the spread of knowledge and education. He believed that investing in education was essential for the growth and development of the community, and so he introduced the idea of a stipend, which was a regular payment given to teachers to support their work. This helped to ensure that teachers could focus on their work and not be discouraged by financial difficulties, and also made it possible for more people to receive an education.
