Celebration

Eid al-Fitr

Eid-ul-Fitr is a spiritual festival marking the end of Ramadan, where Muslims thank Allah for the strength to fast and obey commandments, rejoicing in completing this sacred task rather than its departure. True Islamic sentiment views Ramadan's end with sorrow, as reflected in Imam Zainul-Abedeen's invocation praising its blessings. The festival lifts fasting restrictions but warns against un-Islamic indulgences. It offers three blessings: gratitude to God, self-reflection on character, and obligatory charity to the needy. Special prayers promote universal brotherhood, contrasting religion's elevation of human qualities with materialism's degradation.

Bani Quraiza betrayed their treaty. Ali slew champion Amr bin Abde Wudd in duel. After 20+ days' siege, a divine wind scattered enemies, ensuring Muslim victory despite hypocrites' doubts.
