Ishmael was born in the year 2034, 86 years of Abraham's life, and he lived 137 years. [Whoever sees Ishmael in a dream - his prayer has been heard (Parshat HaRoeh). Ishmael was reincarnated in the donkey of Rabbi Pinchas ben Yair (Emek HaMelech). Ishmael is subject to the moon, and when it is deficient it is a bad sign for him, and when it is full, God forbid, it is a bad sign (Zohar Ki Tetzeh)].
