The word(s) "isma'il" appears 12 time(s) in 12 verse(s) in Quran in Mohsin Khan translation.

(1) And (remember) when We made the House (the Ka'bah at Makkah) a place of resort for mankind and a place of safety. And take you (people) the Maqam (place) of Ibrahim (Abraham) [or the stone on which Ibrahim (Abraham) عليه السلام stood while he was building the Ka'bah] as a place of prayer (for some of your prayers, e.g. two Rak'at after the Tawaf of the Ka'bahat Makkah), and We commanded Ibrahim (Abraham) and isma'il (Ishmael) that they should purify My House (the Ka'bah at Makkah) for those who are circumambulating it, or staying (I'tikaf), or bowing or prostrating themselves (there, in prayer).

(2) And (remember) when Ibrahim (Abraham) and (his son) isma'il (Ishmael) were raising the foundations of the House (the Ka'bah at Makkah), (saying), "Our Lord! Accept (this service) from us. Verily! You are the All-Hearer, the All-Knower."

(3) Or were you witnesses when death approached Ya'qub (Jacob)? When he said unto his sons, "What will you worship after me?" They said, "We shall worship your Ilah (God - Allah), the Ilah (God) of your fathers, Ibrahim (Abraham), isma'il (Ishmael), Ishaq (Isaac), One Ilah (God), and to Him we submit (in Islam)."

(4) Say (O Muslims), "We believe in Allah and that which has been sent down to us and that which has been sent down to Ibrahim (Abraham), isma'il (Ishmael), Ishaq (Isaac), Ya'qub (Jacob), and to Al-Asbat [the offspring of the twelve sons of Ya'qub (Jacob)], and that which has been given to Musa (Moses) and 'Îsa (Jesus), and that which has been given to the Prophets from their Lord. We make no distinction between any of them, and to Him we have submitted (in Islam)."

(5) Or say you that Ibrahim (Abraham), isma'il (Ishmael), Ishaq (Isaac), Ya'qub (Jacob) and Al-Asbat [the offspring of the twelve sons of Ya'qub (Jacob)] were Jews or Christians? Say, "Do you know better or does Allah (knows better ... that they all were Muslims)? And who is more unjust than he who conceals the testimony [i.e. to believe in Prophet Muhammad صلى الله عليه وسلم when he comes, as is written in their Books. (See Verse 7:157)] he has from Allah? And Allah is not unaware of what you do."

(6) Say (O Muhammad صلى الله عليه وسلم): "We believe in Allah and in what has been sent down to us, and what was sent down to Ibrahim (Abraham), isma'il (Ishmael), Ishaq (Isaac), Ya'qub (Jacob) and Al-Asbat [the offspring of the twelve sons of Ya'qub (Jacob)] and what was given to Musa (Moses), 'Îsa (Jesus) and the Prophets from their Lord. We make no distinction between one another among them and to Him (Allah) we have submitted (in Islam)."

(7) Verily, We have sent the revelation to you (O Muhammad صلى الله عليه وسلم) as We sent the revelation to Nuh (Noah) and the Prophets after him; We (also) sent the revelation to Ibrahim (Abraham), isma'il (Ishmael), Ishaq (Isaac), Ya'qub (Jacob), and Al-Asbat [the offspring of the twelve sons of Ya'qub (Jacob)], 'Îsa (Jesus), Ayyub (Job), Yunus (Jonah), Harun (Aaron), and Sulaiman (Solomon); and to Dawud (David) We gave the Zabur (Psalms).

(8) And isma'il (Ishmael) and Al-Yasa' (Elisha), and Yunus (Jonah) and Lut (Lot), and each one of them We preferred above the 'Alamin [mankind and jinn (of their times)].

(9) "All the praises and thanks be to Allah, Who has given me in old age isma'il (Ishmael) and Ishaq (Isaac). Verily! My Lord is indeed the All-Hearer of invocations.

(10) And mention in the Book (the Qur'an) isma'il (Ishmael). Verily he was true to what he promised, and he was a Messenger, (and) a Prophet.
