tahdis

Tahdis is an Arabic term with several related meanings, depending on context. It generally derives from the root ḥ-d-th and is written in transliteration as taḥdīth or tahdith. In everyday Arabic, the word means informing, narrating, or providing information to someone. In modern usage, it also carries the sense of updating or modernizing something, such as data, software, or public information.

In contemporary Arabic and related languages, tahdith commonly refers to the act of giving someone new information or sharing news. It is used in journalistic and administrative contexts to denote updates or refreshes of records, databases, or knowledge. When applied to technology or media, tahdith can mean updating content, upgrading systems, or refreshing information to reflect the latest state.

In Islamic scholarship, taḥdīth is a technical term describing the transmission and narration of hadith. It denotes the process by which a hadith is reported from one generation to another, typically with attention to the chain of transmission (isnad) and the reliability of narrators (rijal). The discipline of taḥdīth involves evaluating reports for authenticity, compiling reliable narrations, and situating them within the broader corpus of hadith literature. This use is distinct from everyday meanings related to informing or updating, though both share the same root.

Overall, tahdis spans everyday communication, information updates, and a specialized scholarly practice in hadith studies.
