Ishaq (Isaac) (Isḥāq) عليه السلام
The Son of Promise and Prophet of Allah
Ishaq (Isaac) (Isḥāq) عليه السلام was one of the noble prophets of Allah and the second son of Ibrahim (Abraham) (Ibrāhīm) عليه السلام. He was born to Sarah in fulfilment of Allah's promise after both she and Ibrahim had reached old age, making his birth one of the great miracles recorded in the Qur'an. Allah not only blessed Ibrahim with a son but also decreed that prophethood would continue through Ishaq and his descendants. Through his son Ya'qub (Jacob) (Yaʿqūb) عليه السلام, Allah raised many of the prophets sent to the Children of Israel, including Yusuf, Musa, Dawud, Sulayman, Zakariyya, Yahya, and Isa عليهم السلام.[1]
Unlike Ibrahim and Musa, the Qur'an records relatively few events from Ishaq's personal life. Instead, it emphasises his miraculous birth, his status as a prophet, his righteousness, and his place within the blessed family chosen by Allah to preserve and spread the message of tawheed. His life demonstrates that prophethood is a gift bestowed solely by Allah and that honour comes through faith and obedience rather than ancestry alone.[2]
The Glad Tidings of Ishaq's Birth
The birth of Ishaq occurred after many years during which Ibrahim and Sarah remained without children. By this time both had reached an advanced age, and Sarah had long believed that she would never bear a child. Allah therefore sent angels to Ibrahim bearing two messages: the impending destruction of the people of Lut and the glad tidings that Sarah would give birth to Ishaq, who would in turn become the father of Ya'qub.[3]
Allah says:
"And his wife was standing, and she laughed. Then We gave her good tidings of Ishaq, and after Ishaq, Ya'qub."
Qur'an 11:71
Surprised by this announcement, Sarah questioned how she could bear a child when both she and her husband had become elderly.
Allah says:
"She said, 'Woe to me! Shall I give birth while I am an old woman and this, my husband, is an old man? Indeed, this is an amazing thing.' They said, 'Are you amazed at the decree of Allah? May the mercy of Allah and His blessings be upon you, O people of the house. Indeed, He is Praiseworthy and Glorious.'"
Qur'an 11:72–73
The angels reminded Sarah that nothing is impossible for Allah. Her pregnancy and the birth of Ishaq were not the result of natural expectation but a manifestation of Allah's power over all things. The miracle demonstrated that Allah grants children according to His wisdom and decree, regardless of human limitations.[4]
The Qur'an also recounts this event elsewhere, describing how the angels informed Ibrahim of the coming birth.
Allah says:
"They gave him glad tidings of a knowledgeable boy."
Qur'an 51:28
Classical Muslim scholars explain that this verse refers to Ishaq, who would become a prophet endowed with wisdom and knowledge. The Qur'an consistently presents his birth as the fulfilment of Allah's promise to Ibrahim and Sarah after years of patience and trust in their Lord.[5]
Ishaq as a Prophet
Allah chose Ishaq as one of His prophets and continued the blessed lineage that began with Ibrahim. Although the Qur'an records little of Ishaq's individual mission, it repeatedly mentions him among the prophets whom Allah selected to guide mankind and preserve the worship of Allah alone.[6]
Allah says:
"And We gave to him Ishaq and Ya'qub, each of whom We guided. And Nuh We guided before; and among his descendants were Dawud, Sulayman, Ayyub, Yusuf, Musa and Harun. Thus do We reward those who do good."
Qur'an 6:84
The Qur'an presents Ishaq as part of a continuous chain of prophets through whom Allah preserved divine guidance across successive generations. His prophethood illustrates that revelation was not limited to isolated individuals but continued through families chosen by Allah, while each prophet remained personally responsible for his own faithfulness and obedience.[7]
Elsewhere, Allah describes Ibrahim, Ishaq, and Ya'qub together as men distinguished by spiritual strength, insight, and constant remembrance of the Hereafter.
Allah says:
"And remember Our servants Ibrahim, Ishaq and Ya'qub, possessors of strength and insight. Indeed, We chose them for an exclusive quality: remembrance of the Home. And indeed, in Our sight they are among the chosen and outstanding."
Qur'an 38:45–47
These verses emphasise that the honour granted to this family was not based merely upon lineage but upon their devotion, sincerity, and unwavering commitment to Allah. They served as examples of faith whose hearts remained focused upon the eternal life to come rather than the temporary attractions of this world.[8]
Ishaq and the Lineage of the Prophets
One of the greatest distinctions granted to Ishaq was that Allah continued the line of prophethood through his descendants. His son Ya'qub became a prophet, and from Ya'qub came the twelve tribes of the Children of Israel. Over many centuries Allah raised numerous prophets from among them, preserving the message of tawheed and repeatedly calling the people back to His guidance whenever they strayed.[9]
Despite this special blessing, the Qur'an consistently teaches that ancestry alone has no value without faith and righteous deeds. While Allah honoured the descendants of Ibrahim through both Ismail and Ishaq, every individual remained accountable for his or her own belief and conduct. The Children of Israel were repeatedly reminded that their covenant with Allah depended upon obedience rather than lineage, just as the descendants of Ismail were required to remain faithful to Allah's guidance.[10]
The life of Ishaq therefore illustrates an important principle found throughout the Qur'an: Allah may grant honour to a family through righteousness, but continued blessing depends upon faith, gratitude, and obedience rather than inherited status. This principle remains central to the Islamic understanding of prophethood and divine justice.[11]
Legacy and Significance
Although the Qur'an records relatively few details of Ishaq's personal life, his importance within Islamic history is profound. Through him, Allah fulfilled His promise to Ibrahim, established a continuing line of prophets, and preserved the message of monotheism among successive generations. His descendants included many of the greatest prophets mentioned in the Qur'an, each continuing the call to worship Allah alone.[12]
The life of Ishaq demonstrates Allah's power to fulfil His promises beyond ordinary human expectation. His miraculous birth to elderly parents stands as a reminder that Allah's decree is never limited by natural causes. At the same time, his story illustrates that true honour lies not in ancestry but in righteousness, faith, and obedience to Allah. Muslims therefore honour Ishaq as one of the noble prophets chosen by Allah, whose life forms an essential link in the continuous chain of revelation leading ultimately to Muhammad ﷺ.[13]
