23ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنِ الْعَلاَءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ سُئِلَ أَبُو عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ الرَّجُلِ يَؤُمُّ الْقَوْمَ فَيَغْلَطُ قَالَ يَفْتَحُ عَلَيْهِ مَنْ خَلْفَهُ.

23. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from al-’Ala’ ibn Razin from Muhammad ibn Muslim who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, was asked about a man who leads people in Salah (prayer) and makes a mistake. He (the Imam) said, ‘Those behind him open it up for him (help to correct him).”’
