Hadith.1113 - Umar ibn Yazid asked Imam Jafar ibn Muhammad Al-Sadiq 
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 replied: "No, do not pray behind him as long as he is not openly defiant and severing ties”.
