It is often used in the context of social, political, or religious discussions to refer to efforts aimed at improving or rectifying certain aspects of society, religion, or personal conduct. The concept of islah is rooted in the idea of making positive changes to address issues, correct wrongdoings, and enhance overall well-being.

The Islahi movement established its organizational presence in Kerala in 1922 through the creation of the Muslim Aikya Sangham (Organization for Muslim Unity). However, it wasn't until 1924, with the formation of the Kerala Jamiyyathul Ulema (KJU), a group of scholars, that the Islahi Movement gained a structured setup and commenced systematic operations within Kerala.

The Islahi scholars were not only spiritual leaders but also prominent figures in the fight for India's independence, actively working to remove foreign rulers from the country. They also aimed to revitalize the spiritual and social aspects of the Muslim community. Notable figures such as Sanaulla Makthi Thangal, K. M. Jamaluddin Moulavi, Chalilakath Kunhahammed Haji, and Vakkom Abdul Qadar Moulavi dedicated their efforts towards these objectives. Leaders like Mohammed Abdul Rahman Sahib, E. K. Moidu Moulavi, and K. M. Seethi Sahib exemplified true Islamic values and motivated every member of society to contribute to the Indian freedom movement.

Adherents of the Islahi movement identify themselves as mujahids in Kerala, which signifies individuals striving for noble causes. It is important to note that the term "Kerala Mujahid" should not be confused with the self-proclaimed mujahids from other parts of the world. The Islahi Movement in Kerala unequivocally opposes all forms of terrorism.

Initially, Islahi scholars recognized that a fundamental need within the Muslim community at that time was educational reform. To address this need, they established an Education Board dedicated to this purpose. This board meticulously set up Madrasas (religious schools) across the state, equipped with modern amenities. These Madrasas stand apart from those in the northern regions of India.

The driving force behind the establishment of significant educational institutions in Kerala, including Arabic colleges, arts and science colleges, technical institutes, and schools, was the Islahi movement's activities.

The movement achieved several significant milestones. Firstly, it published Quran translations and religious texts in the local language, Malayalam. Additionally, the movement introduced Friday sermons (Juma Khutuba) delivered in Malayalam, making them more accessible to the community. Moreover, it played an active role in promoting women's education and their involvement in mosque activities. Another crucial initiative involved the centralized distribution of Zakat funds, providing support to the underprivileged segments of society.

Outside of Kerala, Indian Islahi Centers serve as platforms for followers of the Islahi movement. These centers are active in countries like Saudi Arabia, UAE, Qatar, Oman, Bahrain (Al Furqan Centre), and Kuwait. Recently, Indian Islahi Centers have been established in other Indian cities such as Delhi, Bangalore, and Chennai.
