What made you come, Abu Hidhyam?

Hanzhalah ibn Hidhyam ibn Hanīfah narrates that his grandfather Hanīfah ordered his son Hidhyam to gather his children for him because he wanted to leave a testament before his death. The children gathered, and he told them that the orphan who was in his custody should be given one hundred camels. Before Islam, these camels were called the Mutayyabah, meaning: good camels that people liked for being from among the best camels. Hidhyam told his father that he heard his siblings say that they would approve of their father's will but that they would recant it on his death and would not give the orphan anything. So Hanīfah said that the Messenger of Allah (may Allah's peace and blessings be upon him) would judge between them. Hidhyam said that they were fine with the prospective judgment of the Prophet, may Allah's peace and blessings upon him. So Hidhyam; Hanīfah; and Hanzhalah, the son of Hidhyam — escorting his father — went to the Prophet (may Allah's peace and blessings be upon him) and greeted him. He asked Hanīfah (the father of Hidhyam) what had made him come over to him. Hanīfah pointed to Hidhyam, remarking that he feared that he would die before leaving a testament. He added that the first point of the bequest was that the orphan who was in his custody should be given one hundred camels, which were called, before Islam, the good and favorable ones. On that account, the Messenger of Allah (may Allah's peace and blessings be upon him) became so angry that they discerned that in his face. He changed his sitting position and knelt down. He said that a charity should consist of five camels, or else ten, or else fifteen, or else twenty, or else twenty-five, or else thirty, or else thirty-five, or a maximum of forty. He meant that charity is allowed if it does not exceed the third of one's wealth. They left him, and the orphan had a stick with him wherewith he drove a camel. So the Prophet (may Allah's peace and blessings be upon him) remarked that such a stick was too big for an orphan. By this, he meant that the orphan was a man of a big stature, and it was an exaggeration to call him an orphan, for he was not that young. Hanzhalah said that his grandfather drew him closer to the Prophet (may Allah's peace and blessings be upon him) and said that he had old bearded sons and younger children, and the youngest of them was Hanzhalah, so he asked the Prophet (may Allah's peace and blessings be upon him) to pray for him. The Prophet (may Allah's peace and blessings be upon him) wiped his head and invoked Allah's blessings on him. Dhayyāl, a narrator of this Hadīth, said that he later saw Hanzhalah being brought a man with a swollen face or a beast with sore udders, so he would spit on his hand; say: Bismillāh" (in the name of Allah); put his hand on his head where the Prophet (may Allah's peace and blessings be upon him) had put his hand; and then wipe the affected part of the man or beast, and the tumor would disappear.
