This is for two reasons, one of which is so that the beggar takes it from the hand of the Most Merciful and not from the hand of the one who gives charity.

The Prophet, may God’s prayers and peace be upon him, says that it falls into the hand of the Most Merciful before it falls into the hand of the beggar.

So it is a blessing. God owes the beggar, not the charity, for God asked him for a loan, and the beggar is an interpreter of the right to ask for this loan. The beggar should not be ashamed if he is a believer from the one who gives charity and does not see that he has a favor over him, for the one who gives charity only gave to God for the loan that he asked from him and that he may raise it for him. This is part of divine jealousy, divine favor, and the other matter. To let him know that it is deposited in a place where it is beneficial for him, and all of this is added so that he can be generous by taking it out and avoid his own miserliness .
