Ashura is commemorated by Shi'a Muslims as a day of mourning for the martyrdom of Hussain Ibn Ali, the grandson of prophet Muhammad at the Battle of Karbala, 680 AD.
On Ashura or the day before that (Called Tasua), some specially decorated green cradles, (which many green ribbons and stripes of green fabrics are hung down from them), are placed in different parts of the city; On this day, parents dress their infants or toddlers like Arabs in an Arabic outfit which resembles Ali Asghar (Martyred little son of Imam Hussain); then mothers (sometimes fathers) put their specially dressed infants inside the decorated green cradle, attach some paper money to the crib’s fabric, tie a knot in one of the hanging green ribbons of cradle and make a wish! They promise to God that they will come to the same place next year, if their wish would come true; Therefore, people who have gained what they had asked for, will come to the same cradle next year and this time they untie a knot which has been tied by another person!! They also attach some money to the cradles fabric again, which is a sign of gratitude to the God. After ceremony, collected money will be given to some poor people who are in great need of help.
