Uṣūl al-Ḥadīth helps distinguish Hadith whose authenticity is established from reports whose authenticity is not established.
• This involves investigating both the people who transmitted a report and its wording.
• Its practical aim is to act on authentic Hadith.
• In this way, a person seeks well-being in this world and the Hereafter1.
1. Hereafter: Life after death.
