The Apostle of Allah ﷺ said: When any one of you leads the people in prayer, he should be brief for among them are the young and the aged, the weak and the sick. But when one of you prays by himself, he may (prolong) as he likes.  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا أَمَّ أَحَدُكُمُ النَّاسَ فَلْيُخَفِّفْ فَإِنَّ فِيهِمُ الصَّغِيرَ وَالْكَبِيرَ وَالضَّعِيفَ وَالْمَرِيضَ فَإِذَا صَلَّى وَحْدَهُ فَلْيُصَلِّ كَيْفَ شَاءَ  

This is what Abu Huraira transmitted to us from Muhammad the Messenger of Allah ﷺ, and he narrated (some) ahadith out of (these narrations and one of them is this): The Messenger of Allah ﷺ said: When any one of you stands to lead people In prayer, he should shorten it, for amongst them are the aged, and amongst them are the weak, but when he prays by himself, he may prolong his prayer as he likes.  

عَنْ مُحَمَّدٍ رَسُولِ اللَّهِ ﷺ فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ ﷺ إِذَا مَا قَامَ أَحَدُكُمْ لِلنَّاسِ فَلْيُخَفِّفِ الصَّلاَةَ فَإِنَّ فِيهِمُ الْكَبِيرَ وَفِيهِمُ الضَّعِيفَ وَإِذَا قَامَ وَحْدَهُ فَلْيُطِلْ صَلاَتَهُ مَا شَاءَ  

The Messenger of Allah ﷺ said: When any one of you leads people in prayer, he must shorten it for among them are the weak, the infirm and those who have business to attend.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا صَلَّى أَحَدُكُمْ لِلنَّاسِ فَلْيُخَفِّفْ فَإِنَّ فِي النَّاسِ الضَّعِيفَ وَالسَّقِيمَ وَذَا الْحَاجَةِ  

"When any one of you leads the people in prayer, let him make it short, for among them are the sick, the weak and the elderly. And when any one of you prays by himself, let him make it as long as he wishes."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا صَلَّى أَحَدُكُمْ بِالنَّاسِ فَلْيُخَفِّفْ فَإِنَّ فِيهِمُ السَّقِيمَ وَالضَّعِيفَ وَالْكَبِيرَ فَإِذَا صَلَّى أَحَدُكُمْ لِنَفْسِهِ فَلْيُطَوِّلْ مَا شَاءَ  

When one of you leads the people in prayer, he should be brief, for among them are the weak, the sick, and the aged. But when one of you prays by himself, he may pray as long as he likes.  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا صَلَّى أَحَدُكُمْ لِلنَّاسِ فَلْيُخَفِّفْ فَإِنَّ فِيهِمُ الضَّعِيفَ وَالسَّقِيمَ وَالْكَبِيرَ وَإِذَا صَلَّى لِنَفْسِهِ فَلْيُطَوِّلْ مَا شَاءَ  

when one of you leads the people in prayer, he should be brief, for among them are the sick, the aged and the needy.  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا صَلَّى أَحَدُكُمْ لِلنَّاسِ فَلْيُخَفِّفْ فَإِنَّ فِيهِمُ السَّقِيمَ وَالشَّيْخَ الْكَبِيرَ وَذَا الْحَاجَةِ  

the Prophet said: "When one of you leads the people in prayer then let him be brief, for indeed here are among them the young and the old, the weak and the ill. When one of you prays alone, then let him pray as he wishes."  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا أَمَّ أَحَدُكُمُ النَّاسَ فَلْيُخَفِّفْ فَإِنَّ فِيهِمُ الصَّغِيرَ وَالْكَبِيرَ وَالضَّعِيفَ وَالْمَرِيضَ فَإِذَا صَلَّى وَحْدَهُ فَلْيُصَلِّ كَيْفَ شَاءَ  

Yahya related to me from Malik from Abu'z Zinad from al-Araj from Abu Hurayra that the Messenger of Allah ﷺ said, "When you lead people in the prayer, make it short, because there are among them some people who are weak, ill and old. But when you pray on your own, make it as long as you wish."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا صَلَّى أَحَدُكُمْ بِالنَّاسِ فَلْيُخَفِّفْ فَإِنَّ فِيهِمُ الضَّعِيفَ وَالسَّقِيمَ وَالْكَبِيرَ وَإِذَا صَلَّى أَحَدُكُمْ لِنَفْسِهِ فَلْيُطَوِّلْ مَا شَاءَ  

[Machine] And the Messenger of Allah ﷺ said: "When any of you leads the prayer for the people, let him shorten the prayer, for among them are the old, the weak, and the sick. But when he prays alone, let him prolong his prayer as much as he wishes."  

وَقَالَ رَسُولُ اللهِ ﷺ إِذَا مَا قَامَ أَحَدُكُمْ لِلنَّاسِفَلْيُخَفِّفِ الصَّلَاةَ فَإِنَّ فِيهِمُ الْكَبِيرَ وَفِيهِمُ الضَّعِيفَ وَفِيهِمُ السَّقِيمَ وَإِذَا قَامَ وَحْدَهُ فَلْيُطِلْ صَلَاتَهُ مَا شَاءَ  

Messenger of Allah ﷺ said, "If anyone of you leads the people in the prayer, he should shorten it for amongst them are the weak, the sick and the old; and if anyone among your prays alone then he may prolong (the prayer) as much as he wishes. " (Using translation from Bukhārī 703)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا صَلَّى أَحَدُكُمْ بِالنَّاسِ فَلْيُخَفِّفْ فَإِنَّ فِيهِمُ الضَّعِيفَ وَالسَّقِيمَ وَالْكَبِيرَ وَإِذَا صَلَّى أَحَدُكُمْ لِنَفْسِهِ فَلْيُطَوِّلْ مَا شَاءَ  

[Machine] The Messenger of Allah ﷺ said: "When one of you is the imam, let him shorten the prayer, for behind him are the weak, the elderly, and those in need. But when he prays alone, let him prolong the prayer as much as he wishes."  

قَالَ رَسُولُ اللهِ ﷺ إِذَا كَانَ أَحَدُكُمْ إِمَامًا فَلْيُخَفِّفْ فَإِنَّهُ يَقُومُ وَرَاءَهُ الضَّعِيفُ وَالْكَبِيرُ وَذُو الْحَاجَةِ وَإِذَا صَلَّى لِنَفْسِهِ فَلْيُطَوِّلْ مَا شَاءَ  

When one of you leads the people in prayer, he should be brief, for among them are the weak, the sick, and the aged. But when one of you prays by himself, he may pray as long as he likes. (Using translation from Abū Dāʾūd 794)   

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «إِذَا صَلَّى أَحَدُكُمْ بِالنَّاسِ فَلْيُخَفِّفْ فَإِنَّ فِيهِمُ السَّقِيمَ وَالضَّعِيفَ وَالْكَبِيرَ وَإِذَا صَلَّى أَحَدُكُمْ لِنَفْسِهِ فَلْيُطَوِّلْ مَا شَاءَ»  

"When any one of you leads the people in prayer, let him make it short, for among them are the sick, the weak and the elderly. And when any one of you prays by himself, let him make it as long as he wishes." (Using translation from Nasāʾī 823)  

عَنِ النَّبِيِّ ﷺ قَالَ «إِذَا صَلَّى أَحَدُكُمْ بِالنَّاسِ فَلْيُخَفِّفْ فَإِنَّ فِيهِمُ السَّقِيمُ وَالضَّعِيفُ وَالْكَبِيرُ وَإِذَا صَلَّى أَحَدُكُمْ لِنَفْسِهِ فَلْيُطَوِّلْ مَا شَاءَ»  

When one of you leads the people in prayer, he should be brief, for among them are the weak, the sick, and the aged. But when one of you prays by himself, he may pray as long as he likes. (Using translation from Abū Dāʾūd 794)   

"إذا صلَّى أحدُكُم للنّاسِ فَليُخَفِّفَ، فإِنَّ فيهم الضَّعِيفَ والسقيمَ والكبيرَ، وإذَا صلَّى أحدُكُمْ لنفسِه فَليُطَوِّلْ ما شَاءَ".  

"إذا أَمَّ أحدُكم النَّاسَ فلْيخففْ فإنَّ فيهم الصغيرَ والكبيرَ والضعيفَ والمريضَ وذا الحاجةِ وإِذا صَلّى لنفسِه فلْيطولْ ما شاء".
