Which of the following projects are permissible to spend Zakat funds on, and which are not: digging wells for drinking water, heart surgeries for children from needy families, equipping and operating a health center, food and medical aid, and social assistance for modest families and a patient relief fund?

It is permissible to use Zakat funds to purchase medical supplies or food aid for the poor, provided that these materials are given outright to the poor, especially if it is in their interest. However, spending Zakat on digging wells, building hospitals, or equipping them is not permissible according to the majority of jurists, due to the absence of direct ownership by the poor, though there is a difference of opinion on this matter among some scholars.
