This was narrated by Ahmad ibn Muhammad ibn Isa from al-Husayn ibn Said from Abu Ali, who said:
We were with Abu Abdillah
عليه السلام, peace be upon him, when a man came to Imam
عليه السلام and said: “May I be your ransom. We prayed the Fajr prayer in the mosque, and some of us left while others remained seated in tasbih. Then a man entered the mosque and gave the adhan, so we prevented him and pushed him away from doing that.” Abu Abdillah
عليه السلام, peace be upon him, said: “You did well. Push him away from that and prevent him with the strongest prevention.” I asked: “If they enter and wish to pray in congregation in it?” Imam
عليه السلام said: “Then let them stand in a corner of the mosque, and no imam (of prayer) should step forward among them.” I said to Imam
عليه السلام: “May I be your ransom. We have an imam (of prayer) who is opposed (to us), and he hates all of our companions.” Imam
عليه السلام said: “What concern do you have for what he says? By Allah
سبحانه وتعالى, if you are truthful, then you have more right to the mosque than he does. So be the first to enter and the last to leave, and display good character with the people and speak well.” Then a man asked: “May I be your ransom, the saying of Allah
سبحانه وتعالى, the Exalted: ‘And speak kindly to people’ (Surah Al-Baqarah
2:83), is that meant for all people?” Imam Abu Abdillah
عليه السلام, peace be upon him, laughed and said: “No, what is meant is, ‘Say: (Prophet) Muhammad
صلى الله عليه وعلى آله وسلم is the Messenger of Allah
سبحانه وتعالى, peace be upon him and his family.’”
