Amr bin Sulaym al-Zuraqi (may Allah have mercy on him) reported that it was said to Sayyiduna Umar (may Allah be pleased with him): "There is a boy here from Ghassan, near puberty, who has not yet reached puberty; his heir is in Syria, he is wealthy, and he has no one here except a cousin (the daughter of his paternal uncle)." Sayyiduna Umar (may Allah be pleased with him) said: "Then let him make a bequest for her." So he bequeathed to her a property called Bi'r Jusham. Amr bin Sulaym (may Allah have mercy on him) says: I sold that property for thirty thousand. His cousin, for whom he had made the bequest, was the mother of Amr bin Sulaym.

Abu Bakr bin Muhammad bin Amr bin Hazm (may Allah have mercy on him) says that there was a boy from Ghassan; the time of his death came in Madinah, while his heirs were in Syria. This news reached Sayyiduna Umar (may Allah be pleased with him). It was said: "So-and-so is dying; may he make a bequest?" Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) said: "Let him make a bequest." Abu Bakr bin Muhammad says that the boy was 10 or 12 years old. He bequeathed a property called Bi'r Jusham, and his heirs sold it for 30,000 dirhams.
