Rasulullah (Swallalahu-alayhi Wasallam) said:
“The heart of a person who remains awake (in Ibadah) during the night of Eidul Fitr and Eidul Adha (these are the nights that precede Eid) will not die on the Day when hearts will be dead, i.e. the Day of Qiyamah”.
The nights of both Eids, i.e. the nights preceding the Days of Eid, are auspicious occassions which should be observed with reverence and worship. Rasulullah (Swallalahu-alayhi Wasallam) said that these nights are great occasions of ibadah and of gaining the proximity and special Mercy of Allah. These blessed nights, should therefore not be allowed to pass by in idleness.
Full advantage should be taken of these opportunities by offering obedience and Ibadah unto Allah to the best of our abilities.
Istighfar (seeking forgiveness for sins), Tilawah (reciting the Qur’an), Nafl salaah, durud, etc. should be profusely offered on these blessed nights. Among the rewards which will be obtained as a result of observing the sanctity of these glorious Eid Nights, the greatest reward is the tiding conveyed to us by Rasulullah (Swallalahu-alayhi Wasallam). In the above mentioned Hadith, the heart will be alive on that day when all other hearts will be dead!
