It has been stated by ‘Abdullah ibn ‘Umar (may Allah be pleased with him) that certain of the companions of the Prophet (may Allah’s peace and blessings be upon him) have been shown Laylat al-Qadr in their dreams, which they believe to be during the last seven nights of Ramadan. The Messenger of Allah (may Allah’s peace and blessings be upon him) said: “I notice that your dreams have coincided with each other throughout the course of the past seven nights. Is this a coincidence?” Anyone who want to find it should do so over the final seven nights.”
[According to Al-Bukhari and Muslim] Sahih/authentic.
As a result of the blessings of Allah, the night of Laylat al-Qadr is considered a noble and honorable night in which good acts multiply, sins are forgiven, and matters are decided. When the Companions (may Allah be pleased with them) heard of its significance and prestige, they expressed a desire to know when it would take place. However, Allah, in His wisdom, has concealed the time of its appearance so that people may try to find it with more devotion in prayer, which would, in turn, be beneficial to them. A few Companions had dreams that they were in the final 10 nights of Ramadan, which they believed to be the case. In response to the Messenger’s discovery of this, he stated that, because all of their dreams coincided, it must have occurred during the previous ten nights; therefore, whoever is seeking it should do so during the preceding ten nights, particularly those that are odd (such as the twentieth or the twenty-seventh).
