895. hadíth
وَ سَأَلَ مُعَاوِيَةُ بْنُ وَهْبٍ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلتَّثْوِيبِ اَلَّذِي يَكُونُ بَيْنَ اَلْأَذَانِ وَ اَلْإِقَامَةِ فَقَالَ «مَا نَعْرِفُهُ».
Muawiya ibn Wahb asked Imam Jafar ibn Muhammad Al-Sadiq (a.s) about the practice of "tathwib" (additional announcements or calls made between the adhan and the iqamah). Imam (a.s) replied: "We do not recognize it”.
