Dear respected Shaykh, assalamu alaikum wa rahmatullahi wa barakatuh. The custom in some Moroccan cities is that a person who wishes to rent a house pays an amount of money as a guarantee before renting a house. He gets this money back at the end of the rental contract. This amount of money is above the nisab. Who should pay the Zakat of this amount of money? زكاة مال الضمان
