6ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ عَنْ مُعَاوِيَةَ بْنِ وَهْبٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ التَّثْوِيبِ فِي الأذَانِ وَالإِقَامَةِ فَقَالَ مَا نَعْرِفُهُ.
6. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus from Mu‘awiyah ibn Wahab who said: “I once asked abu ‘Abdillah (a.s.) about tathweeb in the Adhan and ‘Iqamah. He (the Imam) replied, ‘It is unknown to us.”’
