Tahdhīb al-Aḥkām|Volume 2|Book 1|Chapter 13
مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ اَلْحُسَيْنِ عَنْ عَبْدِ اَلرَّحْمَنِ بْنِ أَبِي هَاشِمٍ اَلْبَجَلِيِّ عَنْ سَالِمٍ أَبِي خَدِيجَةَ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: سَأَلَ إِنْسَانٌ وَ أَنَا حَاضِرٌ فَقَالَ رُبَّمَا دَخَلْتُ اَلْمَسْجِدَ وَ بَعْضُ أَصْحَابِنَا يُصَلِّي اَلْعَصْرَ وَ بَعْضُهُمْ يُصَلِّي اَلظُّهْرَ فَقَالَ« أَنَا أَمَرْتُهُمْ بِهَذَا لَوْ صَلَّوْا عَلَى وَقْتٍ وَاحِدٍ لَعُرِفُوا فَأُخِذُوا بِرِقَابِهِمْ»
Muhammad ibn Yahya, from Muhammad ibn Al-Husayn, from Abdul-Rahman ibn Abi Hashim Al-Bajali, from Salim Abu Khadijah, from Abu Abdillah عليه السلام, peace be upon him, who said:
A man asked (Imam عليه السلام) while I was present, and he said: "Sometimes I enter the mosque and some of our companions are praying Asr while others are praying Dhuhr." Imam عليه السلام said: "I am the one who ordered them to do this. If they were to pray at the same time, they would be recognized and seized by their necks."
