Father's Day is celebrated on 13th Rajab, which is Imam Ali's birthday. Imam Ali is the first Shia Imam who was the cousin and son-in-law of Prophet Muhammad. On this day many Iranians gather in various mosques to honor his memory. People are also celebrating fatherhood on this occasion. 13th Rajab is a national holiday just like Mother's Day in Iran.
Iranians spend time with their fathers and grandfathers on the national holiday. It is an excuse for the children to renew visits and pay their respects to their old men. Many people are finding ways to thank their old men. They often pay their respects with small gifts, flowers and cakes.
The father is someone who is always there to trust and depend on.
Happy Father's Day ! :)
