'Umar bin Al-Khattab (May Allah be pleased with him) fixed the payment amounting to four thousand dirhams for each of the early Emigrants, but for his son, he fixed only three thousand five hundred. He was asked: "He is also an (early) Emigrant, why have you fixed a lesser sum for him?" He said: "It was his father who took him along with him. He is not like one who emigrated by himself."[Al-Bukhari].
