913 - وَقَالَ عَلَيْهِ اَلسَّلاَمُ: «كَانَ اِسْمُ اَلنَّبِيِّ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ يُكَرَّرُ فِي اَلْأَذَانِ فَأَوَّلُ مَنْ حَذَفَهُ اِبْنُ أَرْوَى. وَ رُوِيَ: «أَنَّهُ كَانَ بِالْمَدِينَةِ إِذَا أَذَّنَ اَلْمُؤَذِّنُ يَوْمَ اَلْجُمُعَةِ نَادَى مُنَادٍ حُرِّمَ اَلْبَيْعُ لِقَوْلِ اَللَّهِ عَزَّ وَ جَلَّ «يٰا أَيُّهَا اَلَّذِينَ آمَنُوا إِذٰا نُودِيَ لِلصَّلاٰةِ مِنْ يَوْمِ اَلْجُمُعَةِ فَاسْعَوْا إِلىٰ ذِكْرِ اَللّٰهِ وَ ذَرُوا اَلْبَيْعَ» »
Hadith.913 - Imam (as) said: "The name of the Prophet (sw) used to be repeated in the adhan (call to prayer), and the first one to remove it was Ibn Arwa." It is also reported: "In Medina, when the mu'adhdhin (caller to prayer) would make the adhan on Jumu’ah, a caller would announce that trading was forbidden due to the statement of Allah (swt), the Exalted: 'O’ you who believe, when the call is made for prayer on the day of Jumu’ah, hasten to the remembrance of Allah (swt) and leave off trade.'" (Surah Al-Jumu'ah 62:9)
