اَلسَّلَامُ عَلَیْكُمْ اَئِمَّۃَ الْهُدٰی وَ رَحْمَۃُ اللّٰهِ وَ بَرَكَاتُهٗ اَسْتَوْدِعُكُمُ اللّٰهَ وَ اَقْرَئُ عَلَیْكُمُ السَّلَامَ آمَنَّا بِاللّٰهِ وَ بِالرَّسُوْلِ بِمَا جِئْتُمْ بِهٖ وَ دَلَلْتُمْ عَلَیْهِ اَللّٰهُمَّ فَاكْتُبْنَا مَعَ الشَّاهِدِیْنَ۔

The late Shaykh Tusi (r.a.) and Sayyid Ibne Tawoos (r.a.) has said that when you want to say farewell to the Imams (a) of Baqee, you must say:

Then supplicate as much as possible and beg Allah that He again blesses you with their Ziyarat and that it should not be your last Ziyarat and your last time.
