وَ فِي رِوَايَةِ اَلْعَبَّاسِ بْنِ هِلاَلٍ عَنْ أَبِي اَلْحَسَنِ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «مَنْ أَذَّنَ وَ أَقَامَ صَلَّى وَرَاءَهُ صَفَّانِ مِنَ اَلْمَلاَئِكَةِ وَ إِنْ أَقَامَ بِغَيْرِ أَذَانٍ صَلَّى عَنْ يَمِينِهِ وَاحِدٌ وَ عَنْ شِمَالِهِ وَاحِدٌ» ثُمَّ قَالَ «اِغْتَنِمِ اَلصَّفَّيْنِ.
In the narration of Abbas ibn Hilal from Abu Al-Hasan Imam al-Ridha (a.s) said: "Whoever gives the adhan (call to prayer) and the iqamah (second call to prayer) will have two rows of angels praying behind him. If he only recites the iqamah without the adhan, then one angel will pray on his right and one on his left." The Imam then said: "Take advantage of the two rows (of angels)."
