عَنْ أَبِی ھُرَیْرَۃَ، قَالَ قَالَ رَسُولُ اللہِ صَلّی اللہ علیہ وسلم مَنْ یَقُمْ لَیْلَۃَ الْقَدْرِ اِیمَانًا وَاحْتِسَابًا غُفِرَ لَہُ مَا تَقَدَّمَ مِنْ ذَنْبِہِ
Hazrat Abu Hurairah, may Allah be pleased with him, narrates that the Holy Prophet, peace and blessings of Allah be upon him, said:
“Whoever establishes the prayers on the night of Qadr out of sincere faith and hoping to attain Allah’s rewards, then all his past sins will be forgiven.”
(Sahih al-Bukhari, Kitab al-Iman, Hadith 35)
