The hadith of Asim bin Damrah and al-Harith, from Sayyiduna Ali (may Allah be pleased with him), from the Prophet (peace and blessings be upon him) has already passed: "There is no zakah on any wealth until a year has passed over it."
And the hadith of Abdullah bin Mu'awiyah al-Ghadiri from the Prophet (peace and blessings be upon him) has also passed: "There are three things which, whoever does them, has tasted the taste of faith." Then he (peace and blessings be upon him) mentioned those deeds (one of them being:) "and he pays the zakah of his wealth every year with a willing heart, (a zakah) that brings him benefit."
Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) said: When the Prophet (peace and blessings be upon him) passed away, some wealth came to Sayyiduna Abu Bakr (may Allah be pleased with him) from Ibn al-Hadrami. Sayyiduna Abu Bakr (may Allah be pleased with him) said: "Whoever was owed a debt by the Prophet (peace and blessings be upon him), or was promised something by him, let him come to us." Sayyiduna Jabir (may Allah be pleased with them both) said: I said: The Messenger of Allah (peace and blessings be upon him) promised me that he would give me this much and this much — and he spread out his hands three times. I think he (Abu Bakr) said: "Take." So I scooped up a handful, and it was five hundred. Sayyiduna Jabir (may Allah be pleased with them both) said: Then he counted into my hands five hundred, then five hundred. Others added in this narration that he said to Sayyiduna Jabir (may Allah be pleased with them both): "There is no zakah due from you on it until a year has passed over it."
