It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "There is no zakah on less than five wasqs (of grain), there is no zakah on less than five camels, and there is no zakah on less than five uqiyahs (of silver)."
No one narrated this hadith from Layth (may Allah have mercy on him) except Abd al-Warith (may Allah have mercy on him).
