What was the advice given by the Prophet Muhammad (saw) regarding the observance of Lailat-ul-Qadr during the last ten days of Ramadan?
 Ibn Umar (Allah be pleased with them) reported Allah's Messenger (may peace be upon him) as saying:                      Seek it (Lailat-ul-Qadr) in the last (ten nights). If one among you shows slackness and weakness (in the earlier part of Ramadan), it should not be allowed to prevail upon him in the last week.
