question #2 Sahih Muslim 760b, Book 6, Hadith 210 : How does faith and intention impact the acceptance of prayers and forgiveness of sins?

He who prayed on the Lailat-ul-Qadr (the Majestic Night) knowing that it is (the same night). I (believe) that he (the Prophet also) said: (He who does) it with faith and seeking reward (from Allah), his sins would be forgiven.
