Zakat
Book Number: 003 / Hadith Number: 1583
Narated By Jabir ibn Atik : The Prophet (pbuh) said: Riders who are objects of dislike to you will come to you, but you must welcome them when they come to you, and give them a free hand regarding what they desire. If they are just, they will receive credit for it, but if they are unjust, they will be held responsible. Please them, for the perfection of your zakat consists in their good pleasure, and let them ask a blessing for you.
