the survival of the soul after death; an epistle on the prophethood of our Prophet (1) ﷺ; an epistle on the createdness of the universe; an epistle refuting Muḥammad ibn Zakariyyā al-Rāzī with regard to metaphysics and establishing the truth of the Messengers; and an epistle on the stratagems of astrologers.

He (3) then said: He died in 453 AH.
51 – Jaghri Beg, Dāwūd ibn Mīkāʾīl ibn Saljūq al-Turkumānī *
He is Sultan Dāwūd, son of the amir Mīkāʾīl ibn Saljūq ibn Duqāq al-Turkumānī, the Seljuk, ruler of Khurasan; the father of Sultan Alp Arslan; and the brother of Ṭughril Beg, lord of Iraq and Persia. These two were the first Seljuk kings: they seized wide territories and brought the Būyhid dynasty to an end.
Jaghri Beg used to censure his brother for injustice; he himself was known for piety and fairness.
He lived seventy years, and his days lasted until he died at Sarakhs, in Rajab 451 AH. Others said: in Ṣafar 452 AH (4).
His body was then taken to Marw and buried there.
