“Sahl bin Sa’d As-Sa’idi used to give preference to the young to lead his people in prayer. It was said to him: “Do you do that, when you have such seniority (in Islam)?” He said: “I heard the Messenger of Allah ﷺ say: ‘The Imam is responsible. If he does well, then he will have the reward and so will they, but if he does badly, then that will be counted against him but not against them.’”  

ابن ماجة:٩٨١حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا سَعِيدُ بْنُ سُلَيْمَانَ حَدَّثَنَا عَبْدُ الْحَمِيدِ بْنُ سُلَيْمَانَ أَخُو فُلَيْحٍ حَدَّثَنَا أَبُو حَازِمٍ قَالَ كَانَ سَهْلُ بْنُ سَعْدٍ السَّاعِدِيُّ يُقَدِّمُ فِتْيَانَ قَوْمِهِ يُصَلُّونَ بِهِمْ فَقِيلَ لَهُ تَفْعَلُ وَلَكَ مِنَ الْقِدَمِ مَا لَكَ قَالَ إِنِّي

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الإِمَامُ ضَامِنٌ فَإِنْ أَحْسَنَ فَلَهُ وَلَهُمْ وَإِنْ أَسَاءَ يَعْنِي فَعَلَيْهِ وَلاَ عَلَيْهِمْ

[Machine] And he said: I heard the Messenger of Allah ﷺ saying, "No slave leads a group in prayer except that he takes upon himself their responsibility in their prayer. If he performs it well, it is for him and for them. And if he does evil, it is on him and not on them."  

الطبراني:١٥٠٣٧حَدَّثَنَا مُوسَى بْنُ هَارُونَ ثَنَا إِسْحَاقُ بْنُ رَاهَوَيْهِ أَخْبَرَنِي عِيسَى ثَنَا عَبْدُ اللهِ بْنَ عَامِرٍ الْأَسْلَمِيُّ عَنْ أَبِي عَلِيٍّ الْهَمْدَانِيِّ ثُمَامَةَ بْنِ شُفَيٍّ قَالَ كُنَّا مَعَ عُقْبَةَ بْنِ عَامِرٍ الْجُهَنِيِّ فَحَضَرَتِ الصَّلَاةُ فَسَأَلْنَا أَنْ يَؤُمَّنَا فَأَبَى عَلَيْنَا

وَقَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «لَا يَؤُمُّ عَبْدٌ قَوْمًا إلَّا تَوَلَّى مَا عَلَيْهِمْ فِي صَلَاتِهِمْ فَإِنْ أَحْسَنَ فَلَهُ وَلَهُمْ وَإِنْ أَسَاءَ فَعَلَيْهِ وَلَا عَلَيْهِمْ»
