The Command to Sacrifice Ismail

Abraham's vision that he was slaughtering his son, their compliance with the command, and the ransom by the great sacrifice — the story the Qur'an recounts in Sura al-Saffat.

God states in the Qur'an that He showed Abraham in a dream that he was slaughtering Ishmael; he set about fulfilling the command until, when both had submitted and he had laid him on his brow, He called to him that he had fulfilled the vision — and he was ransomed with a great sacrifice (al-Saffat 103–107) ¹.

Genesis mentions that Ishmael was thirteen years older than Isaac, and in al-Mubarakpuri's view the story's context shows it occurred before Isaac's birth, since the tidings of Isaac are given only after the story is fully told ².
