6- حَدَّثَنا مُحَمَّد بن مُوسَى بن المُتِوَكِّل رَضِىَ اللهُ عَنْهُقالَ حَدَّثَنا عَلِيٍّ بن إِبراهِيم بن هاشِمٍ عَن أبِيهِ عَن أبي هاشِمٍ داود بن القاسم الجعفري قالَ سَمِعتُ أبا جَعفَر مُحَمَّد بن عَلِيٍ a.sُ يَقُولُ إِنَّ بَيْنَ جَبَلَيْ طُوسَ قَبْضَةً قُبِضَتْ مِنَ الْجَنَّةِ مَنْ دَخَلَهَا كَانَ آمِناً يَوْمَ الْقِيَامَةِ مِنَ النَّارِ.

66-6 Muhammad ibn Musa ibn al-Mutawakkil - may God be pleased with him - narrated that Ali ibn Ibrahim ibn Hashem quoted on the authority of his father, on the authority of Abi Hashem Dawood ibn Al-Qasim al-Ja’fari that he had heard Aba Ja’far Muhammad ibn Ali (al-Baqir) say, “Indeed there is a piece of land taken from Heaven in between two mountains in Toos. Whoever enters it will be secure from the Fire on the Resurrection Day.”
