When a chapter (of the Quran) is revealed, some people ask others, "Whose faith among you people has received strength from this (revelation)?" It (the revelation) certainly strengthens the faith of the believers and they consider it to be a glad news.
و چون سوره‌اى نازل شود، بعضى مى‌پرسند: اين سوره به ايمان كدام يك از شما درافزود؟ آنان كه ايمان آورده‌اند به ايمانشان افزوده شود، و خود شادمانى مى‌كنند.
