Arabic (Original)
إِنَّمَا الْإِمَامُ جُنَّةٌ فَإِنْ صَلَّى قَاعِدًا فَصَلُّوا قُعُودًا وَإِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَقُولُوا اللَّهُمَّ رَبَّنَا وَلَكَ الْحَمْدُ فَإِذَا وَافَقَ قَوْلُ أَهْلِ الْأَرْضِ قَوْلَ أَهْلِ السَّمَاءِ غُفِرَ لَهُ مَا مَضَى مِنْ ذَنْبِهِ.
English Translation
The imam is only a shield: so if he prays sitting, then pray sitting. And when he says, 'Allah hears whoever praises Him,' then say, 'O Allah, our Lord, to You is all praise.' For when the words of the people of the earth coincide with the words of the people of heaven, his past sins are forgiven.
