Virtue of standing in prayer on Laylat al-Qadr
Hadith 415
وَبِهَذَا، عَنْ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: ((مَنْ قَامَ لَيْلَةَ الْقَدْرِ إِيمَانًا بِاللَّهِ وَتَصْدِيقًا بِهِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ)).
With this same chain (as previous), the Messenger of Allah, peace and blessings be upon him, said: "Whoever stands (in prayer) on the Night of Qadr with faith in Allah and affirming it, his previous sins are forgiven."
