Aboubuker may have claimed some relationship to Mahumud;--he was converted by his preaching from idolatry to the faith;--he gave his daughter in marriage to Mahumud, by whom two sons were born to him, Ishmael and Ibrahim.[9] 'An angel appeared to Mahumud, saying, Which of thy family shall be taken from thee, Oh, Mahumud! such is the command of God; two of thy youth must die, and I am sent to demand of thee whether it is thy wish Ishmael and Ibrahim, thine own sons, shall be taken from this world, or Hasan and Hosein, the sons of Fatima thy daughter?' The historian continues, after dwelling much on the virtues of the Prophet's only daughter, 'Such was the affection of Mahumud for his daughter Fatima and her children, and so well he knew the purity of their hearts, that he hesitated not a moment in replying, "If the Lord graciously permits His servant to choose, I freely offer my two sons Ishmael and Ibrahim; that Hasan and Hosein may live by His mercy "'. Omir was also a convert to the faith Mahumud taught: he likewise gave a daughter in marriage to Mahumud;[10] by whom, however, the same historian remarks, his house was not peopled. His only daughter, Fatima, lived to add numbers to his family: she was born to him by the pious female (a widow) who was his first wife[11] and to whom he was united before he commenced his work of conversion. Ali, to whom Fatima was married, was the nephew of Mahumud, and from this union the Syaad race descend to the present day.

Mahumud's speech to Ali on that occasion is much reverenced by the Sheah sect;--it has been translated for me by my husband, and is as follows:--
