Helpthisjew
Yes because people won’t need Tzaddakah because the world will be a perfected world where there will be no sickness or lack. Tzeddakah is a huge Mitzvah but its only in existence because Hashem wants us to have the great zchus of helping the poor and overcoming our natural tendency to be selfish and hoard our money. When Moshiach comes the Yetzer hars will be greatly lessened and therefore there won’t be much schar for mitzvos done after Moshiach comes so we should chap arein our Mitzvos now!!!
