The Prophet (SAW) has exhorted us to fast during certain days: six days of Shawwal, the Day of Arafah, the day of Ashura, most of the month of Sha’ban, Monday and Thursday, three days of every month, and the fasting of Prophet Dawud.
Allah (SWT) said in the Qur’an:” Whoever follows My guidance, on them shall not be fear, nor shall they grieve.” (2: 38)
Eid al-Fitr is a unique festival. It has neither a connection with any historical event nor is it related to the changes of seasons or cycles of agriculture. It is not a festival related in any way to worldly affairs.
