"تحروا ليلة القدر في الوتر من العشر الأواخر من رمضان"
'Aishah (May Allah be pleased with her) reported: The Messenger of Allah (ﷺ) used to observe I'tikaf in the last ten days of Ramadan and say, "Seek Lailat-ul-Qadr (Night of Decree) in the odd nights out of the last ten nights of Ramadan." [Al- Bukhari] .
