حدثنا عبد الواحد بن محمد بن عبدوس العطار بنيسابور سنة اثنين وخمسين وثلاث مائة قال: حدثا علي بن محمد بن قتيبة، عن حمدان بن سليمان النيسابوري، قال: سألت أبا - الحسن علي بن موسى الرضا عليه السلام عن قول الله عز وجل: " فمن يرد الله أن يهديه يشرح صدره للاسلام   " 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 وعصيانه له 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.
2.	We were told by Abdul-Wahid bin Muhammed bin ‘Abdous al-‘Attar, in Nishapur, year 352, that he said: We were told by Ali bin Muhammed bin Qutayba, from Hamdan bin Sulayman al-Naisabouri, that he said: I asked Abu’l-Hasan, Ali bin Musa al-Rida, peace be upon him, about the saying of Allah, Exalted and Glorious is He: «So, the one whom Allah wants to guide, He expands his chest to Islam» (6:125). He said: The one whom Allah wants to guide with his faith in this world to His Garden and the House of His Generosity in the Hereafter, He will expand his chest to submission to Allah, trust in Him and tranquility towards what He has promised of His reward until he is assured of Him. Moreover, the one whom He wants to lead astray from His Garden and House of Generosity in the Hereafter due to his disbelief and disobedience to Him in this world, He will make his chest tight, aggravated, until he doubts in his disbelief and his heart is distressed from his belief until he becomes as if he is elevating in the sky. Similarly, Allah makes impurity for those who do not believe.
