Hadith 47 1ـ مُحَمَّدُ بْنُ الْحَسَنِ وَعَلِيُّ بْنُ مُحَمَّدٍ عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ عُبَيْدِ الله بْنِ عَبْدِ الله الدِّهْقَانِ عَنْ دُرُسْتَ الْوَاسِطِيِّ عَنْ إِبْرَاهِيمَ بْنِ عَبْدِ الْحَمِيدِ عَنْ أَبِي الْحَسَنِ مُوسَى (عَلَيْهِ السَّلام) قَالَ دَخَلَ رَسُولُ الله (صَلَّى اللهُ عَلَيْهِ وَآلِه) الْمَسْجِدَ فَإِذَا جَمَاعَةٌ قَدْ أَطَافُوا بِرَجُلٍ فَقَالَ مَا هَذَا فَقِيلَ عَلامَةٌ فَقَالَ وَمَا الْعَلامَةُ فَقَالُوا لَهُ أَعْلَمُ النَّاسِ بِأَنْسَابِ الْعَرَبِ وَوَقَائِعِهَا وَأَيَّامِ الْجَاهِلِيَّةِ وَالاشْعَارِ الْعَرَبِيَّةِ قَالَ فَقَالَ النَّبِيُّ (صَلَّى اللهُ عَلَيْهِ وَآلِه) ذَاكَ عِلْمٌ لا يَضُرُّ مَنْ جَهِلَهُ وَلا يَنْفَعُ مَنْ عَلِمَهُ ثُمَّ قَالَ النَّبِيُّ (صَلَّى اللهُ عَلَيْهِ وَآلِه) إِنَّمَا الْعِلْمُ ثَلاثَةٌ آيَةٌ مُحْكَمَةٌ أَوْ فَرِيضَةٌ عَادِلَةٌ أَوْ سُنَّةٌ قَائِمَةٌ وَمَا خَلاهُنَّ فَهُوَ فَضْلٌ.
1. Muhammad b. al-Hasan has narrated from Ali b. Muhammad from Sahl b. Ziyad from Muhammad b. ‘Isa from Ubaydullah al-Dihqan from Durust al-Wasiti from Ibrahim b. Abdul Hamid from Abul Hasan Musa (as) who has said: “Once Rasulullah (sw) entered the Mosque and found a group of people gathered around a man. He asked, 'Who is he?'. It was said that he was a Allamah. He then asked them, 'What is that?'. They replied that he is the most learned man about the genealogy, the chronology, and the history of the pre-Islamic days of darkness and the poetry of Arabs. He (a.s) said, so the Prophet (sw) then stated that ‘such knowledge doesn't harm the one who is ignorant of it or benefit the one who knows it.' Then he (sw) added: ‘Knowledge consists of three kinds: A clear verse (of the Qur'an), a just obligation (i.e. a legal ruling) or an established sunnah (i.e. a hadith). Anything else is of the extra achievements.”’
