Note 426 — Chapter XXVIII · DEATH OF OMAR. A.H. XXIII. A.D. 644.
Reading edition
There is the tradition of a long conversation between Ibn Abbâs and Omar, in which the former pressed the right of his family to the Caliphate; and Omar answered, attributing the claim to envy. The whole is a mere Abbasside invention; for neither Aly nor Abbâs, nor any one of the house of Hâshim, seems even to have dreamed of any such pretension till after the dissensions which broke out after Omar’s death. Fâtima was the only discontented person, and that, as we have seen, was about the property left by the Prophet withheld from her by Abu Bekr, not about any claim to the Caliphate.
