628/813-(Authentic by other than itself, without the reason for the hadith and the haste) From Ibn Abbas who said: The Prophet of Allah, peace and blessings be upon him, came quickly while we were sitting, and his haste towards us startled us. When he reached us, he greeted us with salam, then said: "I came to you quickly to inform you about Laylat al-Qadr, but I forgot it between me and you. So seek it in the last ten nights."
