Does Ismael have any origin in the Islamic faith?

Answer 1

To a limited degree, yes.

First of all, Muslims constitute a religion, not all of whom are of the same ancestry. The 240 million people in Indonesia, for example, are 87% Muslim but not of Ishmaelite descent. The same goes for the 80 million people in Turkey and the 80 million in Iran. Islam spread by conquest and proselytization, not only by growth of the original population.

Secondly, all or part of the Muslim peoples have undergone conquests and contact at the hands of the Crusaders, the Ottomans, the British and others, which will have some bearing on the subject.

If you had asked "Is Ishmael the father of the Arabs," an answer much closer to a simple "yes" could be offered, though it would still not be unequivocal.

The above notwithstanding, Ishmael is spiritually seen as the father of Islam.

Answer 2

Ismael (Ishmael) is the son of prophet Abraham (Ibrahim) who is the father of all prophets including prophet Muhammad (PBUH).

Answer 3

Prophet Ibrahim (or Abraham) is titled as the father of Islam. Prophets Ismael (or Ishmael) and Isaac (or Isshaq) are his sons. Peace be upon them all.
