عَنْ أَنَسٍ قَالَ: مَا صَلَّيْتُ وَرَاءَ إِمَامٍ قَطُّ أَخَفَّ صَلَاةً وَلَا أَتَمَّ صَلَاةً مِنَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَإِنْ كَانَ لَيَسْمَعُ بُكَاءَ الصَّبِيِّ فَيُخَفِّفُ مَخَافَةَ أَنْ تُفْتَنَ أمه

Abu Huraira reported God’s Messenger as saying, “They lead you in prayer, and if they do it properly you will reap a reward, but if they make mistakes you will reap a reward and they will be held responsible. Bukhari transmitted it.
