o dear prophet take the obligatory charity from their wealth by which you may cleanse them and make them pure and pray in their favour indeed your prayer is the contentment of their hearts and allah is all hearing all knowing.
خذ من أموالهم صدقة تطهرهم وتزكيهم بها وصل عليهم إن صلاتك سكن لهم والله سميع عليم
