Imam Al-Husayn’s Sermon before 700 people in Mina-678 CE

Do you know that the Prophet (s) said: "I am the head of all the children of Adam (a) and my brother, Ali (a), is the head of all Arabs, Fatima (a) is the head of all women in the Heaven, and my sons, Hasan and Husayn (a), are the heads of all young people in the Heaven?
