Messenger of Allah ﷺ used to practice Iʿtikaf in the last ten nights of Ramadan and used to say, "Look for the Night of Qadr in the last ten nights of the month of Ramadan."
كَانَ رَسُولُ اللَّهِ ﷺ يُجَاوِرُ فِي الْعَشْرِ الأَوَاخِرِ مِنْ رَمَضَانَ وَيَقُولُ تَحَرَّوْا لَيْلَةَ الْقَدْرِ فِي الْعَشْرِ الأَوَاخِرِ مِنْ رَمَضَانَ
Messenger of Allah ﷺ said, "Search for the Night of Qadr in the odd nights of the last ten days of Ramadan."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ تَحَرَّوْا لَيْلَةَ الْقَدْرِ فِي الْوِتْرِ مِنَ الْعَشْرِ الأَوَاخِرِ مِنْ رَمَضَانَ
Ziyad related to me from Malik from Hisham ibn Urwa from his father that the Messenger of Allah ﷺ said, "Search for Laylat al-Qadr in the last ten days of Ramadan."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ تَحَرَّوْا لَيْلَةَ الْقَدْرِ فِي الْعَشْرِ الأَوَاخِرِ مِنْ رَمَضَانَ
[Machine] The Messenger of Allah ﷺ said, "Seek Laylat al-Qadr (the Night of Power) during the last ten nights of Ramadan."
قَالَ رَسُولُ اللهِ ﷺ تَحَرُّوا لَيْلَةَ الْقَدْرِ فِي الْعَشْرِ الْأَوَاخِرِ مِنْ رَمَضَانَ
[Machine] The Messenger of Allah ﷺ used to retreat in seclusion during the last ten nights and would say, "Seek Laylat al-Qadr (Night of Power) in the last ten nights."
كَانَ رَسُولُ اللهِ ﷺ يَعْتَكِفُ فِي الْعَشْرِ الْأَوَاخِرِ وَيَقُولُ الْتَمِسُوهَا فِي الْعَشْرِ الْأَوَاخِرِ يَعْنِي لَيْلَةَ الْقَدْرِ
[Machine] The Prophet ﷺ said, "Seek out the Night of Decree in the last ten nights of Ramadan."
قَالَ النَّبِيُّ ﷺ تَحَرَّوْا لَيْلَةَ الْقَدْرِ فِي الْعَشْرِ الْأَوَاخِرِ مِنْ رَمَضَانَ
"تَحَرَّوا لَيلَة القَدْر في الوتْرِ مِنَ العَشر الأوَاخرِ مِن رَمَضَان".
