This implication is related to Hazrat Ishmael and Hazrat Ibrahim. It is narrated that Hazrat Ibrahim left Hazrat Hagar and his son Ishmael in the uninhabited area of Mecca by the command of God and settled in Canaan. Sometimes he would go to Mecca to meet them. Abraham came to Mecca for a rainy day and kept dreaming for three consecutive nights that God was asking for the sacrifice of his only son in His way. Abraham willingly obeyed God's command. He told Ishmael the details of the dream and asked for his opinion. Ishmael was well acquainted with the manners of the children.
They went to the forest to obey the order. On the way, Satan repeatedly tried to seduce them but failed. Abraham wanted to obey the command when a voice came from the unseen: "O Abraham, you have made your dream come true. This is how we reward the doers of good." Abraham saw a ram standing. Slaughtered and passed his difficult test. This allusion is used in the following verses.
It was Faizan Nazar or the miracle of the school
Who taught Ishmael child manners?
Muhammad Iqbal
Open your eyes, I will not see you
But I see the knife moving on my neck
