It is narrated from Sayyiduna Muawiyah bin Haydah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: For every forty grazing camels, one bint labun (a two-year-old she-camel) is due as zakat. The camels (shared to avoid zakat) will not be separated. Whoever gives zakat with the intention of reward will receive its reward, and whoever does not pay it, then we will ourselves take it (by force) from him, and (as a penalty) we will also take some of his camels from among his camels, because this is among the obligatory rights of Allah Almighty, and it is not lawful for the family of Muhammad (peace and blessings be upon him) to take anything from it.
