وَ بِهَذَا اَلْإِسْنَادِ عَنْ عَلِيِّ بْنِ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ اَلنَّوْفَلِيِّ عَنِ اَلسَّكُونِيِّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: «اَلاِسْتِنْجَاءُ بِالْيَمِينِ مِنَ اَلْجَفَاءِ».
And through this chain of narration, from Ali bin Ibrahim, from his father, from Al-Nawfali, from Al-Sakuni, from Abu Abdullah عليه السلام, who said:
Imam عليه السلام said: 'Performing istinja (cleansing) with the right hand is an act of rudeness.'
