ذِمَّتي بِمَا أَقُولُ رَهِينَةٌ وَأَنَا بِهِ زَعِيمٌ : إِنَّ مَنْ صَرَّحَتْ لَهُ العِبَرُ عَمَّا بَيْنَ يَدَيْهِ مِنَ المَثُلاتِ، حَجَزَهُ التَّقْوَى عَنْ تَقَحُّمِ الشُّبُهَاتِ. أَلاَ وَإِنَّ بَلِيَّتَكُمْ قَدْ عَادَتْ كَهَيْئَتِهَا يَوْمَ بَعَثَ اللهُ نَبِيَّهُ (صلى الله عليه وآله)،
The responsibility for what I say is guaranteed and I am answerable for it. He to whom experiences have clearly shown the past exemplary punishments (given by Allāh to peoples) is prevented by piety from falling into doubts. You should know that the same troubles have returned to you which existed when the Prophet was first sent.
