18- وَ بِهَذَا الْإِسْنَادِ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنْ عَمْرِو بْنِ شِمْرٍ عَنْ جَابِرٍ عَنْ أَبِي جَعْفَرٍ ع قَالَ: إِنَّ الْعِلْمَ بِكِتَابِ اللَّهِ عَزَّ وَ جَلَّ وَ سُنَّةِ نَبِيِّهِ ص لَيَنْبُتُ فِي قَلْبِ مَهْدِيِّنَا كَمَا يَنْبُتُ الزَّرْعُ عَلَى أَحْسَنِ نَبَاتِهِ فَمَنْ بَقِيَ مِنْكُمْ حَتَّى يَرَاهُ فَلْيَقُلْ حِينَ يَرَاهُ السَّلَامُ عَلَيْكُمْ يَا أَهْلَ بَيْتِ الرَّحْمَةِ وَ النُّبُوَّةِ وَ مَعْدِنَ الْعِلْمِ وَ مَوْضِعَ الرِّسَالَةِ. وَ رُوِيَ أَنَّ التَّسْلِيمَ عَلَى الْقَائِمِ ع أَنْ يُقَالَ لَهُ السَّلَامُ عَلَيْكَ يَا بَقِيَّةَ اللَّهِ فِي أَرْضِهِ.
18 - And from the same chain of narrators from Muhammad bin Sinan from Amr bin Shimr from Jabir from Abi Ja’far 
that he said:
“Knowledge of the book of Allah, the Mighty and Sublime, and the Sunnah of His Messenger develops in the heart of our Mahdi, just as a plant grows to perfection. Thus whosoever of you survives till he sees him, when you meet him you must greet him by the words: “Peace be on you, O folks of the house of mercy and prophethood and the mine of knowledge and the abode of messengership.”
In another narration the Imam is saluted as follows: Peace be on you O the remnant of Allah on His earth.
