The word(s) "ishaq" appears 16 time(s) in 15 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Nay! were you witnesses when death visited Yaqoub, when he said to his sons: What will you serve after me? They said: We will serve your God and the God of your fathers, Ibrahim and Ismail and ishaq, one God only, and to Him do we submit.

(2) Say: We believe in Allah and (in) that which had been revealed to us, and (in) that which was revealed to Ibrahim and Ismail and ishaq and Yaqoub and the tribes, and (in) that which was given to Musa and Isa, and (in) that which was given to the prophets from their Lord, we do not make any distinction between any of them, and to Him do we submit.

(3) Say: We believe in Allah and what has been revealed to us, and what was revealed to Ibrahim and Ismail and ishaq and Yaqoub and the tribes, and what was given to Musa and Isa and to the prophets from their Lord; we do not make any distinction between any of them, and to Him do we submit.

(4) Surely We have revealed to you as We revealed to Nuh, and the prophets after him, and We revealed to Ibrahim and Ismail and ishaq and Yaqoub and the tribes, and Isa and Ayub and Yunus and Haroun and Sulaiman and We gave to Dawood

(5) And We gave to him ishaq and Yaqoub; each did We guide, and Nuh did We guide before, and of his descendants, Dawood and Sulaiman and Ayub and Yusuf and Musa and Haroun; and thus do We reward those who do good (to others).

(6) And his wife was standing (by), so she laughed, then We gave her the good news of ishaq and after ishaq of (a son's son) Yaqoub.

(7) And thus will your Lord choose you and teach you the interpretation of sayings and make His favor complete to you and to the children of Yaqoub, as He made it complete before to your fathers, Ibrahim and ishaq; surely your Lord is Knowing, Wise.

(8) And I follow the religion of my fathers, Ibrahim and ishaq and Yaqoub; it beseems us not that we should associate aught with Allah; this is by Allah's grace upon us and on mankind, but most people do not give thanks:

(9) Praise be to Allah, Who has given me in old age Ismail and ishaq; most surely my Lord is the Hearer of prayer:

(10) So when he withdrew from them and what they worshipped besides Allah, We gave to him ishaq and Yaqoub, and each one of them We made a prophet.
