1217 - فَقَدْ رَوَى مُحَمَّدُ بْنُ أَبِي عُمَيْرٍ عَنْ أَبِي عَلِيٍّ اَلْحَرَّانِيِّ قَالَ: كُنَّا عِنْدَ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ فَأَتَاهُ رَجُلٌ فَقَالَ صَلَّيْنَا فِي مَسْجِدٍ اَلْفَجْرَ فَانْصَرَفَ بَعْضُنَا وَ جَلَسَ بَعْضٌ فِي اَلتَّسْبِيحِ فَدَخَلَ عَلَيْنَا رَجُلٌ اَلْمَسْجِدَ فَأَذَّنَ فَمَنَعْنَاهُ وَ دَفَعْنَاهُ عَنْ ذَلِكَ فَقَالَ أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ «أَحْسَنْتُمْ اِدْفَعُوهُ عَنْ ذَلِكَ وَ اِمْنَعُوهُ أَشَدَّ اَلْمَنْعِ» فَقُلْتُ لَهُ فَإِنْ دَخَلَ جَمَاعَةٌ فَقَالَ «يَقُومُونَ فِي نَاحِيَةِ اَلْمَسْجِدِ وَ لاَ يَبْدُو لَهُمْ إِمَامٌ.
Hadith.1217 Muhammad ibn Abi Umayr narrated from Abu Ali al-Harrani who said:
“We were with Imam Jafar ibn Muhammad Al-Sadiq 
when a man came and said:
"We prayed Fajr in the mosque, and some of us left while others stayed for tasbih (glorification). Then, a man entered the mosque and began to give the adhan. We prevented and stopped him from doing that."
Abu Abdullah said: "You did well to stop and prevent him firmly."
I asked him, "What if a group enters?"
Imam said: "They should pray in a corner of the mosque without appointing an Imam”.
