قُلْتُ لَهُ أَ يُصَلِّي الرَّجُلُ وَ هُوَ مُتَلَثِّمٌ فَقَالَ أَمَّا عَلَى الْأَرْضِ فَلَا وَ أَمَّا عَلَى الدَّابَّةِ فَلَا بَأْسَ.
“I once asked abu Ja‘far (a.s.), about a man’s performing Salah (prayer) with his face veiled. He (the Imam) said, ‘It is not permissible while on the ground; however, while riding on a stumper is not an offense.’”
