Assalamu Alaykum wa Rahmatu Allahi wa Barakatuh

My answer is NO. Charities receive Zakah on agency basis from Zakah payers; they cannot use part of Zakah for its administration. This is as if the Zakah payer himself takes part to himself for giving it to the poor. Allah in the Qur’an ordered us to give the Zakah  and be sure that it reaches its destination. This is why we cannot take any wage for ourselves to make it reach to poor. Only a government has the right to activate the item of worker on Zakah العاملون عليها in distribution Zakah to the deserving categories as mentioned in the Verse 9:60 of the Qur’an.

Wa Allahu A’alam
