٤ - حدثنا عبد الواحد بن محمد بن عبدوس العطار رضي الله عنه بنيسابور سنة اثنتين وخمسين وثلاثمائة، قال: حدثنا علي بن محمد بن قتيبة، عن حمدان بن سليمان النيسابوري، قال: سألت أبا الحسن علي بن موسى الرضا عليهما السلام، (بنيسابور) (١) عن قول الله عز وجل: ﴿فمن يرد الله أن يهديه يشرح صدره للإسلام﴾  قال: من يرد الله أن يهديه بإيمانه في الدنيا إلى جنته ودار كرامته في الآخرة يشرح صدره للتسليم لله والثقة به والسكون إلى ما وعده من ثوابه حتى يطمئن إليه، ومن يرد أن يضله عن جنته ودار كرامته في الآخرة لكفره به وعصيانه في الدنيا يجعل صدره ضيقا حرجا حتى يشك في كفره، ويضطرب من اعتقاده قلبه حتى يصير كأنما يصعد في السماء كذلك يجعل الله الرجس على الذين لا يؤمنون .  باب الرد على الثنوية والزنادقة 
4. `Abd al-Wahid ibn Muhammad ibn `Abdus al-`Attar (may Allah be pleased with him) said in Naysabur year 352 AH that `Ali ibn Muhammad ibn Qutaybah said, on the authority of Hamdan ibn Sulayman al-Naysaburi that I asked Abu al-Hasan `Ali ibn Musa al-Rida  in Naysabur about the Word of Allah, the Mighty and High: Therefore, (for) whomsoever Allah intends that He would guide him aright, He expands his breast for Islam. He clarified, Whoever Allah intends to guide with faith in Him in this world, and to His Paradise and abode of Kindness in the Hereafter, He expands his breast in submission to Allah, trust in Him, and satisfaction with His Promises and Rewards until He is tranquil And whosoever He intends that He should cause him to err from His Paradise and abode of His Kindness in the Hereafter for his disbelief and disobedience of Allah in this world, He makes his breast strait and narrow so that he doubts due to his disbelief, and his heart is confused concerning his faith until he becomes as though he were ascending upwards; thus, does Allah lay uncleanness on those who do not believe.
