Haritha bin Abi al-Rajal حارثة بن أبي الرجال · Obligatory Charity Tax (Zakat)

I heard the Prophet (ﷺ) saying, "O people! Give in charity as a time will come upon you when a person will wander about with his object of charity and will not find anybody to accept it, and one (who will be requested to take it) will say, "If you had brought it yesterday, would have taken it, but today I am not in need of it."

I heard the Prophet (p.b.u.h) saying, "(O people!) Give in charity (for Allah's cause) because a time will come when a person will carry his object of charity from place to place (and he will not find any person to take it) and any person whom he shall request to take it, I will reply, 'If you had brought it yesterday I would have taken it, but today I am not in need of it."
