Each 'Eid is a Day of remembrance.
Even in their most joyful times the Muslims make a flesh stall of the Day by a plural session of worship to Allah.
They pray to Him and glorify His name to demonstrate their remembrance of His favours.
Along with that course, they remember the deceased by prayer for their souls, the needy by extending a hand of help, the grieved by showing them sympathy and consolation, the sick by cheerful visits and utterances of good wishes, the absentees by cordial greetings and sincere considerateness, etc.
Thus the meaning of remembrance on the Day transcends all limits and expands over far-reaching dimensions of human life.
