It is narrated from Hazrat Ubadah bin Samit (may Allah be pleased with him) that he asked the Holy Prophet (peace and blessings be upon him) about Laylat al-Qadr. The Holy Prophet (peace and blessings be upon him) said: "It occurs in the month of Ramadan. Seek it in the last ten nights of Ramadan, for it is in the odd nights—21st, 23rd, 25th, 27th, 29th, or the last night. And whoever stands (in prayer) on this night with faith and seeking reward, and attains this night, then all his past and future sins are forgiven."
