Know that the unbelievers are being addressed by the basis of the Sharia, which is belief in all that the Messenger brought from God, of the news and the principles of the rulings and their branches, which is his saying, may God’s prayers and peace be upon him, and believe in me and in what I have brought

which is action according to what The discourse necessitated it from action and omission, so belief in voluntary charity is that it is obligatory voluntary charity and is one of the principles of Sharia, and giving voluntary charity is a branch, and there is no difference between it and obligatory charity in believing in it and in giving it, even if they are not equal in reward, then that does not discredit the principle. If they differ in one way, then they are united in the stronger way.
