Search Laylatul-Qadr in the last ten
تَحَرَّوْا لَيْلَةَ الْقَدْرِ فِي الْوِتْرِ مِنَ الْعَشْرِ الْأَوَاخِرِ مِنْ رَمَضَانَ
Taharraw laylata-l-qadri fi-l-witri mina-l-'ashri-l-awakhiri min Ramadan.
"Seek the Night of Decree in the odd nights of the last ten of Ramadan."
Narrated by 'A'ishah. Sahih al-Bukhari 2017, Sahih Muslim 1169
A short reflection
The Prophet ﷺ didn't pin it to one night. He taught us to search, that effort is part of the reward.
