24 - حَدَّثَنا الحَسَن بْنِ أَحْمَدِ بْنِ إِدْرِيس عَنْ أَبيهِ عَنْإِبْراهيمِ بْنِ هاشِم عَنْ مُحَمَّدِ بْنِ حفص عَنْ حَمْزَة بْنِ جَعْفَر الأرجانِي قالَ خَرَجَ هَارُونُ مِنَ الْمَسْجِدِ الْحَرَامِ مَرَّتَانِ وَخَرَجَ الرِّضَا a.sُ مَرَّتَانِ فَقَالَ الرِّضَا a.sُ مَا أَبْعَدَ الدَّارَ وَأَقْرَبَ اللِّقَاءَ يَا طُوسُ سَتَجْمَعُنِي وَإِيَّاهُ.

47-24 Al-Hassan ibn Ahmad ibn Idris - may God be pleased with him - narrated that his father quoted on the authority of Ibrahim ibn Hashem, on the authority of Muhammad ibn Hafs, on the authority of Hamza ibn Ja’far al-Arjani, “Harun departed from one of the gates of Masjid ul-Haram (the House of God) and Ar-Ridha’ left from another gate. Ar-Ridha’ said the following to Harun for him to take heed to, ‘How far away is the (eternal) Abode and how close is the meeting in Toos (where both Harun and Ar-Ridha’ will be buried)! O Toos! O Toos! Soon you will bring me and him (referring to Harun) together.’”
