Perform 'Umra and Ḥajjs sincerely in order to cleanse oneself from sin and gain rewards in paradise.

This hadith from Abu Huraira speaks about the rewards of performing both Umrah and Hajj. It states that performing an 'Umrah is an expiation for any sins committed between it and the next 'Umra, while a successful Ḥajj will be rewarded with nothing less than Jannah. This hadith emphasizes the importance of these two acts in Islam as they are seen as a way to cleanse oneself from their sins. It also highlights how great a reward one can receive if they perform these acts with sincerity, as Jannah is promised to those who do so successfully.
