The Prophet (SAWA) said, 'The voluntary pilgrimage (Aumra) expiates all sins committed since the preceding voluntary pilgrimage, and the reward for an accepted obligatory pilgrimage (Hajj) is Paradise. There are certain sins that can only be forgiven on the plains of Aarafa [part of the obligatory pilgrimage].
رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ): العُمرَةُ إلى العُمرَةِ كَفّارَةُ ما بَينَهُما ، والحجّةُ المُتَقَبَّلَةُ ثوابُها الجَنَّةُ ، ومِنَ الذُّنوبِ ذنوبٌ لا تُغفَرُ إلّا بعَرَفاتَ.
