وَ رَوَى عَنْهُ عَبْدُ اَلرَّحْمَنِ بْنُ أَبِي عَبْدِ اَللَّهِ أَنَّهُ قَالَ: «إِذَا صَلَّيْتَ فَصَلِّ فِي نَعْلَيْكَ إِذَا كَانَتْ طَاهِرَةً فَإِنَّ ذَلِكَ مِنَ اَلسُّنَّةِ.
It is narrated from Him (Imam Al-Sadiq عليه السلام) through Abd al-Rahman ibn Abi Abdillah that Imam عليه السلام said: "If you pray, then pray in your sandals (shoes) if they are clean, for that is from the Sunnah."
