Validity Measurement of WAQF Related Research in Scopus Indexed Journals: A Rabbani Approach Analysis

This study has two underlying objectives. The first is to identify the validity measurement utilized in waqf-related research in Scopus indexed journals. The second is to formulate the measurement validity through Rabbani approach based on a waqf-related daleel (evidence) extracted from the al-Quran. Validity is the most important element in research. A research is accepted as true or otherwise through validity. One of the principles in ensuring validity is the use of measurement from the same source. The validity measurement required in waqf-related research must be sourced from al-Quran and al-Sunnah since the concept of waqf is an instrument derived from Islam. This is vital in ensuring truth in the process of validating the research. The question is, what types of measurement validity are employed in waqf-related research published in Scopus index journals? Is the measurement in tandem with the Rabbani approach considering that waqf is an Islamic instrument? This research attempts to answer both questions through archival research, content analysis as well as textual analysis conducted on several literature. For the first question, the research ascertained three validity measurement approaches used in the Scopus indexed journals. As for the second question, the research found that the Rabbani approach was used as the main validity instrument for waqf-related research. These findings serve as a guidance to other researchers who conduct waqf-related research by employing the Rabbani approach as the main research validity measurement.
