It is related from ʿAmru bin Shuʿaib from his father, from his grandfather that, 'The Prophet addressed the people and said, "Are there those among you who are guardians of orphans who possess property? Then let them trade therewith, and not leave it (uninvested), so that the alms due on it do not swallow it up."'—At Tirmidhí.
It is related from Abú Hurairah that he said, 'When the Prophet died and Abú Bakr succeeded him as Khalífa, and certain of the Arabs became infidels, ʿOmar binuʾl-Khaṭṭáb said to Abú Bakr, "How is it that thou dost fight with the people when the Apostle of God has said, 'I was commanded to fight with the people until they say, "There is no God but Alláh," and whoever says, "There is no God but Alláh," makes his goods and his person safe from me, except what is due (as alms); and his account-is with God?'" Then Abu Bakr replied, "By God! I will certainly fight with those who make a distinction between prayers and alms; for alms are due from property. By God! if they had denied me a lamb, such as they used to give to the Prophet of God, I would certainly have fought with them because of such refusal." ʿOmar said, "By God! I saw nothing, except that God had opened the heart of Abú Bakr to fight. Then I knew it was right."'—Muslim, Al Bukhárí.
Concerning the Things on which Alms are
Obligatory
It is related from Abú Saʿíduʾl-Khudri that, 'The Apostle of God said, "There are no alms required for less than five camel-loads of dates, and no alms are required for less than five uqiyas, (i.e. three hundred drams) of silver, and no alms are required for less than five camels."'—Muslim, Al Bukhárí.
It is related from Abú Hurairah that, 'The Apostle of God said, "A Muslim is not obliged to give alms for his slave or his horse." And in another tradition it runs, "There is no alms for his slave, except the alms for the feast of the breaking the fast."'—Muslim, Al Bukhárí.
It is related from Muʿádh that he said, 'Verily the Prophet when he sent him to Yemen, commanded him to take one yearling heifer or bull from every thirty, and one full-grown cow from every forty.'—Abú Dáud, At Tirmidhí.
