Standing for the Salat/Prayers
فَانْطَلَقَا حَتَّىٰ إِذَا أَتَيَا أَهْلَ قَرْيَةٍ اسْتَطْعَمَا أَهْلَهَا فَأَبَوْا أَنْ يُضَيِّفُوهُمَا فَوَجَدَا فِيهَا جِدَارًا يُرِيدُ أَنْ يَنْقَضَّ فَأَقَامَهُ ۖ قَالَ لَوْ شِئْتَ لَاتَّخَذْتَ عَلَيْهِ أَجْرًا {77}
So, they went on until when they came to the people of a town. They asked its people for food, but they refused to host them. Then they found a wall therein about to break down, so he ‘فَأَقَامَهُ’ straightened it. He (Musa) said, ‘If you so desire, you could take a recompense upon it’ [18:77]
مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ عَنْ صَالِحِ بْنِ عُقْبَةَ عَنْ أَبِي هَارُونَ الْمَكْفُوفِ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ ( عليه السلام ) يَا أَبَا هَارُونَ الْإِقَامَةُ مِنَ الصَّلَاةِ فَإِذَا أَقَمْتَهُ فَلَا تَتَكَلَّمْ وَ لَا تُومِ بِيَدِكَ
