It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that some companions of the Noble Prophet (peace and blessings be upon him) saw in their dreams that Laylat al-Qadr was in the last seven nights. So the Prophet (peace and blessings be upon him) said: "I see that your dreams coincide regarding the last seven nights, so seek it in the last seven nights."
