The holy prophet Muhammad’s grandson, Imam Husayn (PBUH) gave everything he had to save the whole mankind. He revived Islam by his blood to save the humanity, therefore each year, Shia Muslim people across the world donate blood on the martyrdom anniversary of Imam Husayn (PBUH) on the day of Ashura
Ashura is the tenth day of Muharram in the Islamic calendar. On Ashura
day, Imam Husayn, the holy prophet Muhammad’s grandson and all 72 of
his companions including his six-month-old infant, Hazrat Ali Asghar,
were killed in the battle of Karbala.
Shia Muslim and other Imam Husayn’s lovers commemorate the day of Ashura by taking part in mourning ceremonies and processions held worldwide.
