This research uses historical approach method and content analysis technique to the existing written data. This research found that the credibility of Shaykh 'Abdurrahman Ya'qub as a scholar is inseparable from his involvement in the scholars network. It turned out that Shaykh 'Abdurrahman Ya'qub had inherited knowledge from the great scholars, among others Shaykh Sa'id Yamani (1265-1352 AH.), Shaykh Muhammad' Ali al-Maliki (1287-1368 AH.), Shaykh 'Umar Hamdan (1292-1368 AH.), Shaykh Hasan bin Muhammad al-Masysyath (1317-1399 AH.), and Shaykh Muhammad Yasin al-Fadani (1335-1410 AH.).
