"And when he attained the age of running with him (Ibrahimpeace and blessings be upon him), he said: "O my son verily I have seen in a dream that I am slaughtering thee, so look, considerest thou?" He said: "O my father! Do that which thou art commanded, thou shalt find me, Allah willing, of the patients."

"Then when the two submitted themselves and had prostrated him on his temple."

"We cried unto him: "O Ibrahim! Of a surety thou hast fulfilled the vision. Verily We! That was a trial manifest. And We ransomed him with a mighty victim. And We left for him among the posterity. Peace be unto Ibrahim. Verily We! Thus we compense the well doers. Verily he was one of Our believing bondsmen." (37:102-111)
Thus this very incident is also the origin of ‘Takbeer-e-Tashreeq’.

Eminent jurispudents have stated that the origin of the ‘Takbeer-e-Tasreeq’ is when the Prophet Ibrahim peace and blessings be upon him made Hazrat Ismail peace and blessings be upon him lie down, Allah ordered Hazrat Jibraeel peace and blessings be upon him to take along a ‘fidyah’(ransom) and when Hazrat Jibraeel peace and blessings be upon him arrived there, he feared that Hazrat Ibrahim peace and blessings be upon him would slaughter Ismail peace and blessings be upon him and so he began shouting "Allah Akbar, Allah Akbar."

Hearing his voice, Prophet Ibrahim peace and blessings be upon him took it as a glad tiding and exclaimed, "Laa ilaaha allallahu wallahu akbar."

Hazrat Ismail peace and blessings be upon him also came to know that the ‘fidyah’ arrived and he got up saying, "Allahu akbar wa lillahil hamd," and began to eulogise and thank Allah.
