Note 418 — Chapter XXVIII · DEATH OF OMAR. A.H. XXIII. A.D. 644.
Reading edition
By some authorities he was now sixty-three; but this was a favourite age with traditionists, being that at which the Prophet died (supra, p. 119). He was born before the ‘Sacrilegious War,’ which lasted ten years, A.D. 580–590 (Life of Mahomet, p. 14); but his birth was probably at the end of the last great battle, which terminated that war. This would make him twenty-six at his conversion, and fifty-five at his death. If born at the commencement of the war, he would now be ten years older. The true date may lie between the two extremes; and it is not unlikely that he was near sixty years of age at his death.
