why then do you not say the same regarding one who abandons the prayer? The ruling is the same: “But if they repent, establish prayer, and give zakah, then they are your brothers in faith.” [At-Tawbah: 11]
The answer is that specific texts establish the disbelief of one who abandons the prayer; it is on this basis that we judge him to be a disbeliever. The texts concerning the disbelief of one who abandons the prayer stand independently, and there is no counter-evidence capable of opposing them. Whatever has been claimed to constitute opposing evidence does not challenge the proofs for his disbelief, whether in authenticity or in implication.
The individual and social benefits and wisdoms of zakah include the following:
First: it completes and perfects the servant’s Islam, for it is one of the pillars of Islam. When a person fulfills it, his Islam is complete and perfected. Undoubtedly, this is a great objective for every Muslim, for every believing Muslim strives to perfect his religion.
Second: it is evidence of the sincerity of the zakah-giver’s faith. Wealth is beloved to people, and what is beloved is not given up except in pursuit of something equally beloved or greater—indeed, in pursuit of something more beloved than it. For this reason, it is called sadaqah (charity), because it demonstrates the sincerity with which its giver seeks the pleasure of Allah, Glorified and Exalted is He.
Third: it refines the character of the zakah-giver, lifting him from the ranks of the miserly and placing him among the generous. When a person trains himself to give—whether by imparting knowledge, spending wealth, or using his influence—that giving becomes an ingrained disposition and natural habit. He even feels distressed if a day passes in which he has not given as he is accustomed to doing. This is like a hunter who is accustomed to hunting: if he is kept from hunting that day, he feels constricted at heart. Likewise, one who has trained himself in generosity feels distressed whenever a day passes in which he has not offered his wealth, influence, or benefit to others.
