`Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) said: Seek Laylat al-Qadr in the last ten nights of Ramadan, and if one shows weakness or is unable, then do not be negligent in the last seven nights.

The hadith of Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) regarding this chapter has already been mentioned (see Hadith: 632).
