وَإِذَا قُمْتَ فِي صَلَاتِكَ لِلنَّاسِ، فَلَا تَكُونَنَّ مُنَفِّراً وَلَا مُضَيِّعاً، فَإِنَّ فِي النَّاسِ مَنْ بِهِ الْعِلَّةُ وَلَهُ الْحَاجَةُ. وَقَدْ سَأَلْتُ رَسُولَ اللهِ (صلى الله عليه وآله) حِينَ وَجَّهَنِي إِلَى الْيَمَنِ كَيْفَ أُصَلِّي بِهِمْ؟ فَقَالَ: «صَلِّ بِهِمْ كَصَلَاةِ أَضْعَفِهِمْ، وَكُنْ بِالْمُؤْمِنِينَ رَحِيماً».
When you lead the prayers for the people it should be neither (too long as to be) boring nor (too short as to be) wasteful, because among the people there are the sick as well as those who have needs of their own. When the Messenger of Allāh (S) sent me to Yemen I enquired how I should offer prayers with them and he replied, “Say the prayers as the weakest of them would say, and be considerate to the believers.”
