Sayyiduna Abdullah bin Umar (may Allah be pleased with him) says: People would see various dreams and narrate them before the Messenger of Allah (peace and blessings be upon him). One day, the Prophet (peace and blessings be upon him) said: I am hearing your dreams; they correspond to the last seven nights of Ramadan. Therefore, whoever among you wishes to seek Laylat al-Qadr should seek it in the last seven nights.
