Chapter: 34, Verse: 18:

عدة من أصحابنا ، عن أحمد بن محمد بن خالد ، عن أبيه ، عن محمد بن سنان عن زيد الشحام قال : دخل قتادة بن دعامة على أبي جعفر ( عليه السلام ) فقال : يا قتادة أنت فقيه أهل البصرة ؟ قال : هكذا يزعمون فقال أبو جعفر ( عليه السلام ) : بلغني أنك تفسر القرآن ؟

فقال له قتادة : نعم ، فقال له أبو جعفر ( عليه السلام ) بعلم تفسره أم بجهل ؟ قال : لا بعلم ، فقال له أبو جعفر ( عليه السلام ) : فإن كنت تفسره بعلم فأنت أنت وأنا أسألك ؟ قال قتادة : سل قال : أخبرني عن قول الله عز وجل في سبأ : " وقدرنا فيها السير سيروا فيها ليالي وأياما آمنين" فقال قتادة : ذلك من خرج من بيته بزاد حلال وراحلة وكراء حلال يريد هذا البيت كان آمنا حتى يرجع إلى أهله ، فقال أبو جعفر ( عليه السلام ) : نشدتك الله يا قتادة هل تعلم أنه قد يخرج الرجل من بيته بزاد حلال وراحلة وكراء حلال يريد هذا البيت فيقطع عليه الطريق فتذهب نفقته ويضرب مع ذلك ضربة فيها اجتياحه ؟ قال قتادة : اللهم نعم ، فقال أبو جعفر ( عليه السلام ) : ويحك يا قتادة إن كنت إنما فسرت القرآن من تلقاء نفسك فقد هلكت وأهلكت وإن كنت قد أخذته من الرجال فقد هلكت وأهلكت ، ويحك يا قتادة ذلك من خرج من بيته بزاد وراحلة وكراء حلال يروم هذا البيت عارفا بحقنا يهوانا قلبه كما قال الله عز وجل : " واجعل أفئدة من الناس تهوي إليهم" ولم يعن البيت فيقول : إليه ، فنحن والله دعوة إبراهيم ( عليه السلام ) التي من هوانا قلبه قبلت حجته وإلا فلا ، يا قتادة فإذا كان كذلك كان آمنا من عذاب جهنم يوم القيامة ، قال قتادة : لا جرم والله لا فسرتها إلا هكذا ، فقال أبو جعفر ( عليه السلام ) : ويحك يا قتادة إنما يعرف القرآن من خوطب به

A number of our companions, from Ahmad Bin Muhammad Bin Khalid, from his father, from Muhammad Bin Sinan, from Zayd Al-Shahaam who said:

Qatada Bin Da'ama came up to Abu Jafar Imam Mohammad Baqir (as), so the Imam (as) said, "O Qatada! Are you a Faqih (Jurist) of the people of Basra?"

He said, "That is what they are alleging".

Imam (as) said, "It has reached Me that you are explaining the Quran".

Qatada said, "Yes".

So Imam (as) said to him, "You are explaining it by knowledge or by ignorance?"

He said, "No, by knowledge".

So Imam (as) said to him, "So if you are explaining by knowledge, so ‘you are’ ‘who you are’ and I would like to ask you’.

Qatada said, "Ask".

Imam (as) said, "Inform Me about the saying of Allah (swt), "And We apportioned the journey therein: Travel through them nights and days, secure" (34:18).

Qatada said, "That is for the one who goes out from his house with lawful provisions, and camel rented lawfully intending this House (Kabah). He would be safe until he returns back to his family".

So Imam Baqir (as) said, "I hold you to Allah (swt), O Qatada! Do you know that if the man comes out from his house with lawful provisions, and a camel rented lawfully, intending this House, he could get cut off (by bandits) on the road, and his provisions would be lost and he could be injured due to that?"

Qatada said, "O Allah (swt), Yes!"

So Imam Baqir (as) said, "Woe be unto you! If you are explaining the Quran from your own free will, so you are destroyed and causing others to be destroyed. And if you have taken it from the men (others), you have been destroyed and so have they.

Woe be unto you! (But) that (verse) is for the one who comes out from his house with provisions, and lawful means of transportation aspiring for this House while having recognized Our rights, & his heart inclined towards Us, just as Allah (swt) has said, "Therefore make the hearts of some people inclined towards them" (14:37) and it does not mean the House (Kabah), for Allah (swt) is saying ‘towards them’.  So We are, by Allah (swt), the supplication of Ibraheem (as) (in this verse) towards whom whose heart is inclined, his Pilgrimage would be accepted, otherwise it will not be, O Qatada! So if it is like that, he would be safe from the Punishment of Hell on the Day of Judgement."

Qatada said, "No offence. By Allah (swt), I will not explain it except like this".

So Imam Baqir (as) said, "Woe be unto you, O Qatada! But rather, those understand the Quran who have been addressed by it".

Chapter: 34, Verse: 19:

قَالَ مُحَمَّدُ بْنُ الْعَبَّاسِ رَحِمَهُ اللَّهُ حَدَّثَنَا مُحَمَّدُ بْنُ أَحْمَدَ بْنِ ثَابِتٍ عَنِ الْقَاسِمِ بْنِ إِسْمَاعِيلَ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنْ سَمَاعَةَ بْنِ مِهْرَانَ عَنْ جَابِرِ بْنِ يَزِيدَ عَنْ أَبِي جَعْفَرٍ ع‌ فِي قَوْلِ اللَّهِ عَزَّ وَ جَلَ‌ إِنَّ فِي ذلِكَ لَآياتٍ لِكُلِّ صَبَّارٍ شَكُورٍ قَالَ صَبَّارٍ عَلَى مَوَدَّتِنَا وَ عَلَى مَا نَزَلَ بِهِ مِنْ شِدَّةٍ أَوْ رَخَاءٍ صَبُورٍ عَلَى الْأَذَى فِينَا شَكُورٍ لِلَّهِ عَلَى وَلَايَتِنَا أَهْلَ الْبَيْتِ

Chapter: 34, Verse: 28 - Can Imams (as) see everything from east to west?

قُلْتُ جُعِلْتُ فِدَاكَ فَهَلْ يَرَى الْإِمَامُ مَا بَيْنَ الْمَشْرِقِ وَ الْمَغْرِبِ فَقَالَ يَا ابْنَ بَكْرٍ فَكَيْفَ يَكُونُ حُجَّةَ اللَّهِ عَلَى مَا بَيْنَ قُطْرَيْهَا وَ هُوَ لَا يَرَاهُمْ وَ لَا يَحْكُمُ فِيهِمْ وَ كَيْفَ يَكُونُ حُجَّةً عَلَى قَوْمٍ غُيَّبٍ لَا يَقْدِرُ عَلَيْهِمْ وَ لَا يَقْدِرُونَ عَلَيْهِ وَ كَيْفَ يَكُونُ مُؤَدِّياً عَنِ اللَّهِ وَ شَاهِداً عَلَى الْخَلْقِ وَ هُوَ لَا يَرَاهُمْ وَ كَيْفَ يَكُونُ حُجَّةً عَلَيْهِمْ وَ هُوَ مَحْجُوبٌ عَنْهُمْ وَ قَدْ جَعَلَ بَيْنَهُمْ وَ بَيْنَهُ أَنْ يَقُومَ بِأَمْرِ رَبِّهِ فِيهِمْ وَ اللَّهُ يَقُولُ وَ ما أَرْسَلْناكَ إِلّا كَافَّةً لِلنّاسِ يَعْنِي بِهِ مَنْ عَلَى الْأَرْضِ وَ الْحُجَّةُ مِنْ بَعْدِ النَّبِيِّ (ص) يَقُومُ مَقَامَ النَّبِيِّ (ص) مِنْ بَعْدِهِ 

I (narrator) asked, "May I sacrifice myself for you. Can the Imam (as) see everything from the East to the West?"

Imam Sadiq (as) said, "O Son of Bukayr, How can he be the decisive Proof of Allah (swt) over the entire earth without seeing and ruling over everyone? And how can he be the Decisive Proof over people if they are hidden from Him, who cannot reach him and over whom he has no power? How can he convey the message of Allah and act as Allah's witness over the creation if he cannot see them? How can he be the Decisive Proof on the people if he is hidden from them? while he has been appointed as the medium between the slaves and Allah (swt) so that he carries out the orders of his Lord to them?

And Allah (swt) says, "We have not sent you but to all mankind" (34:28). This verse refers to everything on earth. The Decisive Proof after the Messenger of Allah (swt) fills the post of the Messenger of Allah (swt) after him.
