Supplication during the Night of Decree
It is recommended to supplicate often during all times, especially during the month of Ramadan, in the last ten nights, and during the odd nights of it even more so. It is recommended that one say the following supplication a lot:
"O Allah! Verily, you are the Oft-Pardoning, You love to pardon, so pardon me."
This is due to what Imam Ahmad recorded from Aishah that she said "O Messenger of Allah! If I find the Night of Al-Qadr what should I say?" He (saws) replied,
Say : "O Allah! Verily You are the Oft-Pardoning, You love to pardon, so pardon me."
