The gematria of the Hebrew name ישמעאל (Yishmael) is 451; it is equal to that of both Hebrew names אברם (Abram), 243 dan הגר (Hagar) 208. Thus, the gematria of ישמעאל (Yishmael) is 451, the same as that of אברם והגר (Abram ve Hagar), 451. Abraham is the father of Ishmael, Hagar is the mother of Ishmael. Hagar bore Ishmael for Abraham. Meanwhile, the gematria of the Hebrew name הגר (Hagar) is 208, the same as that of the title of Abram as אב המון (av hamon), 208; the phrase literally means “a father of a multitude” see Sefer Bereshit 17:4-5. Amazingly, the Arabic name اسمعيل (Isma’il) appears 12 times in the Holy Quran. It means that the Quran also confirms the gematria of Ishmael in the Torah. In the Sefer Bereshit (Genesis) 17:20, LORD said to Abraham: 

ולישמעאל שמעתיך הנה אתו במאד מאד שנים עשר נשיאם יולד ונתתיו לגוי גדול: 

u-le Yishma'el shema'ticha hinneh berachti oto ve hifreiti oto ve hirbeiti oto be-meod meod sheneim 'ashar nesi'im yolid le goy gadol. 

"But regarding Ishmael I have heard you, I have blessed him, made him fruitful and will increase him most exceedingly; he will beget twelve princes and I will make him into a great nation." 

Interestingly, based on the verse, three keywords textually appear in one sentence: ישמעאל (Yishmael), במאד מאד (be-meod meod), and שנים עשר (sheneim ‘ashar), and the readers have to understand it most attentively. The gematria of ישמעאל (Yishmael) is 451, and the gematria of במאד מאד (be-meod meod) is 92. Thus, the gematria of ישמעאל (451), lit. “Yishmael” and the gematria of במאד מאד (92), lit. “most exceedingly” totally is 543 (5 + 4 + 3 = 12), the same as that of the term שנים עשר (sheneim ‘ashar), lit. “twelve.” Also, the gematria of ישמעאל (Yishmael) is 451, and the gematria of מחמד (Muhammad), lit. “most preciously” is 92, thus both names have a value 543 (5 + 4 + 3 = 12), the same of that of the term שנים עשר (sheneim ‘ashar), lit. “twelve.” Indeed, the Torah has a link with the Quran in the light of gematria about Ishmael.

The first, the name of ישמעאל (Yishmael) directly refers to the phrase במאד מאד (be-meod meod), lit. “most exceedingly” which has a relation to the phrase שנים עשר נשיאם (sheneim ‘ashar nesi’im), lit. “the twelve princes.” The second, the name of ישמעאל (Yishmael) indirectly refers to the name מחמד (Muhammad), lit. “most preciously” which has a relation to the phrase שנים עשר נשיאם (sheneim ‘ashar nesi’im), lit. “the twelve princes.”

Based on the Sefer Bereshit 17:20, the gematria of the phrase במאד מאד (be-meod meod), lit. “most exceedingly” is 92, the same as that of the next phrase לגוי גדול (le goy gadol), 92; and this phrase literally means “to be a great nation.” Amazingly, both phrases directly refer to the same, the offspring of ישמעאל (Yishmael). The gematria of ישמעאל – במאד מאד (Yishmael – be meod meod), is 543, it is equal to that of ישמעאל – לגוי גדול (Yishmael – le goy gadol); and both phrases have a relation to the phrase שנים עשר נשיאם (sheneim ‘ashar nesi’im), lit. “the twelve princes.” Similarly, the gematria of the phrase לגוי גדול (le goy gadol) is 92; and this phrase literally means “to be a great nation.”
