One of the benefits of Zakāt is that it fortifies wealth

The Messenger of Allāh (may Allāh praise him and Peace be upon him) said, “Fortify your wealth by giving Zakāt (compulsory charity), treat your sick by way of Ṣadaqah (optional charity) and welcome the waves of trials by supplicating and humbly asking of Allāh.” [Abū Dāwūd]
