وَ قَالَ أَبُو جَعْفَرٍ لِمُحَمَّدِ بْنِ مُسْلِمٍ يَا مُحَمَّدَ بْنَ مُسْلِمٍ لَا تَدَعَنَّ ذِكْرَ اللَّهِ عَلَى كُلِّ حَالٍ وَ لَوْ سَمِعْتَ الْمُنَادِيَ يُنَادِي بِالْأَذَانِ وَ أَنْتَ عَلَى الْخَلَاءِ فَاذْكُرِ اللَّهَ عَزَّ وَ جَلَّ وَ قُلْ كَمَا يَقُولُ الْمُؤَذِّنُ.

Hadith.892 - Imam Muhammad ibn Ali Al-Baqir (as) said to Muhammad ibn Muslim: "O’ Muhammad ibn Muslim, never neglect the remembrance of Allah (swt) in any situation. Even if you hear the caller calling the adhan while you are in a state of relieving yourself, remember Allah (swt), the Mighty and Majestic, and say what the mu'adhdhin says."
