It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Seek Laylat al-Qadr on the seventeenth, or the nineteenth, or the twenty-first, or the twenty-third, or the twenty-fifth, or the twenty-seventh, or the twenty-ninth (nights)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abu al-Muhazzim (may Allah have mercy on him) except Sulaym (may Allah have mercy on him)."
