887. hadíth
وَ رُوِيَ: «أَنَّ مَنْ صَلَّى بِأَذَانٍ وَ إِقَامَةٍ صَلَّى خَلْفَهُ صَفَّانِ مِنَ اَلْمَلاَئِكَةِ وَ مَنْ صَلَّى بِإِقَامَةٍ بِغَيْرِ أَذَانٍ صَلَّى خَلْفَهُ صَفٌّ وَاحِدٌ وَ حَدُّ اَلصَّفِّ مَا بَيْنَ اَلْمَشْرِقِ وَ اَلْمَغْرِبِ.
It is narrated: "Whoever prays with both the adhan (call to prayer) and iqamah (second call to prayer), two rows of angels pray behind him. And whoever prays with just the iqamah without the adhan, one row of angels prays behind him, and the extent of the row is from the east to the west."
