Selection of suitable place like the Raas al-Hussein (the place where the head of Imam al-Hussein [a] is buried), or any other sacred place is another etiquette and manner of supplication, which has been mentioned in some of the traditions; supplication at such places undoubtedly possesses more distinction and is more nearer to be granted.
 Imam Hussein [a]: The younger son of the Commander of the Faithful Imam 'Ali [a] and Fatimah al-Zahra [a] - the daughter of the Holy Prophet [s] - Fatimah al-Zahra was born in Madina on Thursday 3rd Sha'ban 4 A.H; like his brother he lived most of his life quietly in Madina under the watchful eyes of the Caliph's officials and spies. When Mu'awiyyah's son Yazid became caliph, he demanded allegiance from Imam al-Hussein [a], who refused to give it. Finally Imam al-Hussein [a] felt it necessary to go into battle against Yazid to protest against the injustices which were being carried out in the name of Islam. He and a small group of followers including most of his immediate family were cruelly massacred at Karbala. The day of his martyrdom is 10th Muharram, 61 A.H. "Ashura has become the most solemn day of the Islamic calendar, marked by processions and universal mourning. He is buried in Karbala in Iraq [Tr].
