[9/62] Ma’ani al-Akhbar: With the above chain from Ibn Isa from Ibn Abi Umayr from Ibn Udhayna from Burayd al-Ijli who said: I said to Abi Abdillah عليه السلام: what is the least thing by which the slave becomes Kafir? So he took a pebble from the ground and said: that he says about this pebble ‘it is a date-stone’ and goes on to disassociate from anyone who opposes him in that, and he worships Allāh by disassociating from the one who professes a belief other than his own, so this is a hostile opponent who has ascribed partners to Allāh and disbelieved without knowing.

[9/62] معاني الاخبار: وبهذا الاسناد عن ابن عيسى، عن ابن أبي عمير، عن ابن اذينة، عن بريد العجلي قال: قلت لابي عبد الله عليه السلام: ما أدنى ما يصير به العبد كافرا؟ قال: فأخذ حصاة من الارض فقال: أن يقول لهذه الحصاة: إنها نواة، ويبرء ممن خالفه على ذلك، ويدين الله بالبراءة ممن قال بغير قوله، فهذا ناصب قد أشرك بالله وكفر من حيث لا يعلم
