878 - وَ سَأَلَ مُحَمَّدُ بْنُ مُسْلِمٍ أَبَا جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلرَّجُلِ يُؤَذِّنُ وَ هُوَ يَمْشِي وَ هُوَ عَلَى غَيْرِ طُهْرٍ أَوْ هُوَ عَلَى ظَهْرِ اَلدَّابَّةِ قَالَ «نَعَمْ إِذَا كَانَ اَلْمُتَشِّهِدُ مُسْتَقْبِلَ اَلْقِبْلَةِ فَلاَ بَأْسَ.
Hadith.878 - Muhammad ibn Muslim asked Imam Muhammad ibn Ali Al-Baqir 
about a man who gives the adhan (call to prayer) while walking, while not in a state of ritual purity, or while riding an animal.
The Imam said: "Yes, it is permissible if the one giving the testimony of faith (in the adhan) faces the Qiblah; there is no issue."
