Hadith 448[333/5] الخزاز، عن أبي الحسن الرضا عليه السلام قال: إن رسول الله صلى الله عليه واله يوم القيامة آخذ بحجزة الله، ونحن آخذون بحجزة نبينا، وشيعتنا آخذون بحجزتنا. ثم قال: الحجزة: النور
5. [5/333] al-Tawhid and al-Uyun: My father from Sa’d from Ibn Isa from al-Hasan b. Ali al-Khazzaz from Abi al-Hasan al-Ridha عليه السلام who said: The Messenger of Allah صلى الله عليه واله will hold on to the waist-knot of Allah on the Day of Judgment, we will hold on to the waist-knot of our prophet, and our Shia (followers) will hold on to our waist-knot. Then he said: waist-knot means light.
