Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "Whoever wishes to seek it, let him seek it on the twenty-seventh night." And he said: "Seek it on the twenty-seventh night!" The narrator says: the Prophet (peace and blessings be upon him) meant Laylat al-Qadr.
(Allamah Haythami says:) I say: From Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) a hadith other than this one is recorded in the Sahih.
Ahmad recorded it, and its narrators are the narrators of the Sahih.
