5. It is narrated from the narrator of the previous Hadith from al-Nadr ibn Suwayd from al-Qasim ibn Sulayman from Jarrah al- Mada’iniy who has narrated the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said, ‘An oath is not taken by anything other than by Allah.’ He (the Imam) said, ‘In the case of Jews, Christians and Zoroastrian, you must not make them to take an oath by anything other than by Allah, most Majestic, most Glorious.””
