What is the authenticity of the Hadith: "The people of the Maghreb will remain manifest upon the truth until the Hour is established"?

The Hadith (definition): "The people of the West will remain manifest upon the truth until the Hour (Day of Judgment) is established." Narrators differed in its wording between "Ahl al-Gharb" (people of the West) and "Ahl al-Maghrib" (people of the Maghreb/west), but scholars tend towards the first wording due to its prevalence in ancient Sunan books.

Scholars differed in defining "Ahl al-Gharb" with several interpretations: 1. The Arabs: Because "al-Gharb" refers to the large bucket, and Arabs were known for using it. 2. The Mujahideen (holy warriors): Because "al-Gharb" here means intensity and sharpness, and the Mujahideen are characterized by endurance and perseverance. 3. The people of Sham (Greater Syria) and beyond: Because Medina used to call Sham "Gharb" (west), and other Hadiths interpreted the manifest group as the people of Sham or the environs of Jerusalem. Egypt might also be included. 4. The Scholars: Because "al-Gharb" can mean the abundance of tears shed out of fear of Allah due to knowledge, and scholars are the people who fear Allah the most.
