"And mention Isma'il in the Book, surely he was truthful in (his) promise, and he was a Messenger, a Prophet."[19:54]
The Isma'il referred to by Allāh in the above verse is not the Prophet Isma'il (alayhi salām) the son of Prophet Ibraheem (alayhi salām), but is another Prophet from among the Prophets of Allāh. He was chosen by Allāh for his people, who tortured him to such an extent, that they peeled the skin off his head and face. An Angel descended unto him and said, "Allah the glorious has sent me to you, ask whatever is your heart's desire."
The Prophet replied, "I am sympathetic towards whatever will befall Husain (alayhi salām)."
