١١ - وبهذا الإسناد، عن ابن أبي عمير، عن محمد بن حمران، عن أبي عبيدة الحذاء، قال: قال لي أبو جعفر عليه السلام: يا زياد إياك والخصومات فإنها تورث الشك وتحبط العمل وتردي صاحبها، وعسى أن تكلم بالشئ فلا يغفر له، إنه كان فيما مضى قوم وتركوا علم ما وكلوا به وطلبوا علم ما كفوه حتى انتهى كلامهم إلى الله عز وجل فتحيروا، فإن كان الرجل ليدعى من بين يديه فيجيب من خلفه ويدعى من خلفه فيجيب من بين يديه. 
11. And with the same chain of transmission, on the authority of Ibn Abu `Umayr, on the authority of Muhammad ibn Humran, on the authority of Abu `Ubaydah al-Hadhdha’ that Abu Ja`far al-Baqir (A)S said: O Ziyad! Beware of quarrels. Verily, its legacy is doubt and the loss of good deeds. A quarrelling person gets ruined. It may be that he talks about something for which he will not be forgiven. Verily, he may become lie the people of the past, who avoided the knowledge they were given, thinking that their knowledge would suffice. Their speech ended with Allah, the Mighty and High. Thus, they became so much bewildered that when a man was called from the front, he would answer from behind, and if he was called from behind, he would answer from in front.
