390 – Salamah ibn Shabīb narrated to me that ʿAbd Allāh ibn Wahb told him, from Bakr ibn Muḍar, from ʿUmārah ibn Ghaziyyah, who said: I heard a man ask Rabīʿah, “Abū ʿUthmān, what is the essence of asceticism?” He replied, “To acquire things by their rightful means and to place them where they rightfully belong.”
