It is narrated that when Hazrat Ibrahim (a.s) felt that the knife is not cutting, and that the command for the sacrifice has been rescinded by Allah, he cried. Hazrat Jibraeel (a.s.) came to him and asked, " Why are you crying?" He said, " I think I am not fit enough that my sacrifice was not acceptable to Allah!" Jibraeel (a.s.) said, " You have successfully gone through all the stages of the sacrifice. Your heart even then cries that it has not reached its conclusion." Then Hazrat Jibraeel (a.s) told Hazrat Ibrahim (a.s.) about the hardships and the supreme sacrifice in store for Imam Hussain (a.s)!
