Hadith.1113 - Umar ibn Yazid asked Imam Jafar ibn Muhammad Al-Sadiq (as) about an Imam who is generally good in all his affairs and knowledgeable, but he raises his voice and speaks harshly to his parents, causing them distress. He asked: "Should I pray behind him?" He (as) replied: "No, do not pray behind him as long as he is not openly defiant and severing ties”.
