"Whoever performs wudu and performs wudu, well, then prays ('Abdur-Rahman said: and prays Isha), then prays after that four Rakahs and does them well (Sawwar said: and understands what he is reciting (Sawwar said: and recites therein), they will be equivalent to (praying) Lailat Al-Qadr for him". (Hasan Maqtu) (Using translation from Nasāʾī 4954)
وَقَالَ سَوَّارٌ ثُمَّ صَلَّى الْعِشَاءَ الْآخِرَةَ ثُمَّ صَلَّى بَعْدَهَا أَرْبَعَ رَكَعَاتٍ فَأَتَمَّ وَقَالَ سَوَّارٌ يُتِمُّ رُكُوعَهُنَّ وَسُجُودَهُنَّ وَيَعْلَمُ مَا يَقْرَأُ وَقَالَ سَوَّارٌ يَقُولُ فِيهِنَّ كُنَّ لَهُ بِمَنْزِلَةِ لَيْلَةِ الْقَدْرِ
