Allah the Almighty told us of Abraham's affliction with his beloved son: And he said (after his rescue from the fire): "Verily, I am going to my Lord. He will guide me! My Lord! Grant me (offspring) from the righteous." So We gave him the glad tidings of a forbearing boy. And, when he (his son) was old enough to walk with him, he said: "0 my son! I have seen in a dream that I am slaughtering you (offer you in sacrifice to Allah), so look whatdo you think!" He said: "0 my father! Do that which you are commanded, Insha' Allah (if Allah wills), you shall find me of the patient."

Then, when they had both submitted themselves (to the Will of Allah) and he had laid him prostrate on his forehead (or on the side of his forehead for slaughtering); and We called out to him: "0 Abraham! You have fulfilled the dream (vision)!" Verily! Thus do We reward those who perform good deeds totally for Allah's sake only. Verily, that indeed was a manifest trial - and We ransomed him with a great sacrifice (i.e. a ram); and We left for him (a goodly remembrance) among generations (to come) in later times. "Salaamun (peace) be upon Abraham!" Thus indeed do We reward the Muhsineen (good-doers). Verily, he was one of Our believing slaves. Surah 37:99-111

Time passed. One day Abraham was sitting outside his tent, thinking of his son Ishmael and Allah's sacrifice. His heart was filled with awe and love for Allah for His countless blessings. A big tear dropped from his eyes and reminded him of Ishmael.
