Takaful is an Islamic alternative to conventional insurance that is based on mutual cooperation and donation rather than commercial transactions. It involves participants contributing to a common fund as a tabarru (donation) to be used to compensate members in case of valid claims. This spreads risk among members and draws from historical systems like aaqilah. Takaful minimizes issues of riba, gharar and maisir by operating through tabarru rather than interest-based investments. General takaful provides short-term coverage through contributions invested and profits shared according to set ratios to cover operational costs.
