To search for the Night of Qadr in the odd nights

عَنْ عَائِشَةَ رَضِىَ اللهُ عَنْهَا، أَنَّ رَسُولَ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ

‏ تَحَرَّوْا لَيْلَةَ الْقَدْرِ فِى الْوِتْرِ مِنَ الْعَشْرِ الْأَوَاخِرِ مِنْ رَمَضَانَ

Hazrat Aisha^ra narrates that the Holy Prophet^sa said:

“Search for the Night of Qadr in the odd nights of the last ten days of Ramadan.”

(Sahih al-Bukhari, Kitab Fazl Lailatul Qadr, Hadith 2017)
