bayhaqi:9774Abū Zakariyyā b. Abū Isḥāq > Abū al-Ḥasan Aḥmad b. Muḥammad b. ʿAbdūs > ʿUthmān b. Saʿīd al-Dārimī > ʿAbdullāh b. Ṣāliḥ > Muʿāwiyah b. Ṣāliḥ > ʿAlī b. Abū Ṭalḥah

[Machine] In His saying {Indeed, the postponing of sacred months is an increase in disbelief} [Surah At-Tawbah 37], An-Nasii' said that Junadah ibn 'Awf ibn Umayyah Al-Kinani used to perform Hajj every year, and he was known as Abu Thumamah. He would call out, "Indeed, Abu Thumamah is neither praised nor blamed." Indeed, in the year of Safar, he would declare it to be permissible for the people, thus making it forbidden for the next year, and he would also declare Muharram to be forbidden for the following year. That is what Allah the Almighty has said, {Indeed, the postponing of sacred months is an increase in disbelief by which those who have disbelieved are led [further] astray. They make it lawful one year and unlawful another year} [Surah At-Tawbah 37], until His saying, {He does not guide the disbelieving people} [Surah Al-Baqarah 264].  

البيهقي:٩٧٧٤أَخْبَرَنَا أَبُو زَكَرِيَّا بْنُ أَبِي إِسْحَاقَ ثنا أَبُو الْحَسَنِ أَحْمَدُ بْنُ مُحَمَّدِ بْنِ عَبْدُوسٍ ثنا عُثْمَانُ بْنُ سَعِيدٍ الدَّارِمِيُّ ثنا عَبْدُ اللهِ بْنُ صَالِحٍ حَدَّثَنِي مُعَاوِيَةُ بْنُ صَالِحٍ عَنْ عَلِيِّ بْنِ أَبِي طَلْحَةَ عَنِ ابْنِ عَبَّاسٍ

فِي قَوْلِهِ تَعَالَى {إِنَّمَا النَّسِيءُ زِيَادَةٌ فِي الْكُفْرِ} [التوبة 37] قَالَ النَّسِيءُ أَنَّ جُنَادَةَ بْنَ عَوْفِ بْنِ أُمَيَّةَ الْكِنَانِيَّ كَانَ يُوَافِي الْمَوْسِمَ كُلَّ عَامٍ وَكَانَ يُكَنَّى أَبَا ثُمَامَةَ فَيُنَادِي أَلَا إِنَّ أَبَا ثُمَامَةَ لَا يُحَابُ وَلَا يُعَابُ أَلَا وَإِنَّ عَامَ صَفَرٍ الْأَوَّلِ الْعَامَ حَلَالٌ فَيُحِلُّهُ لِلنَّاسِ فَيُحَرِّمُ صَفَرًا عَامًا وَيُحَرِّمُ الْمُحَرَّمَ عَامًا فَذَلِكَ قَوْلُهُ تَعَالَى {إِنَّمَا النَّسِيءُ زِيَادَةٌ فِي الْكُفْرِ يُضَلُّ بِهِ الَّذِينَ كَفَرُوا يُحِلُّونَهُ عَامًا وَيُحَرِّمُونَهُ عَامًا} [التوبة 37] إِلَى قَوْلِهِ {لَا يَهْدِي الْقَوْمَ الْكَافِرِينَ} [البقرة 264]
