UPDATE : Night 29 Ramadan 2021 :
These reports are not authentic and there is no established source for “Lailatul Ja’izah”. While it is always recommended to do Qiyaamul Layl, there is no sound basis for a specific significance of the nights preceding the Eids.

…um… OOPS!
Laylat al-Jaiza or Night of Rewards is the night preceding both the Eid al-Fitr and Eid al-Adha.
It has particular significance with the month of Ramadan and is to earn rewards for all the fasts and good deeds in this month.
It is considered as a blessed night for Muslims and a night to offer prayers and supplications.
Prophet Muhammad (upon who be peace) is reported to have said in a hadith in Sunan ibn Maja.
“Whoever stands up (in worship) in the nights preceding the two Eids expecting rewards from his Lord,
his heart will not die when the other hearts will die.”
I recorded this video on Laylatul Jaiza Night 30 of Ramadan 2018 in Vancouver’s Al Jamia Masjid.
Before the Imam began leading the prayer, he reminded us about Laylatul Jaiza and encouraged us not to let it pass by us . . .
