Sheikh Kafa'ami said: reporting from the Ahlulbayt (peace be on them): repeat the following supplication on the twenty third night of the holy month of Ramadan, either in prostration, or standing or sitting position or in any other condition, even at any time of the month or any time of the year, you recite the supplication after praising Allah the Most High and sending blessing to His Prophet (peace and blessing be on him and on his family).

بِسْمِ اﷲِ الرَّحْمٰنِ الرَّحِیْمِ

Bismillaahir-Rahmaanir-Raheem

In the name of Allah the Beneficent the Merciful.

اَللّٰهُمَّ كُنْ لِوَلِيِّكَ الْحُجَّةِ بْنِ الْحَسَنِ، (صَلَوَاتُكَ عَلَيْهِ وَعَلٰى اٰبَاۤئِهِ)، فِيْ هٰذِهِ السَّاعَةِ وَفِيْ كُلِّ سَاعَةٍ، وَلِيًّا وَحَافِظًا، وَقَاۤئِدًا وَنَاصِرًا، وَدَلِيْلًا وَعَيْنًا، حَتَّى تُسْكِنَهُ اَرْضَكَ طَوْعًا، وَتُمَتِّعَهُ فِيْهَا طَوِيْلًا۔

Allahumma kun li waliyyika al-Hujjat ibn al-Hasan (salawatuka ‘alayhi wa ‘ala aaba’ihi), fi hadhihi as-sa’ah wa fi kulli sa’ah, waliyyan wa hafizan, wa qa’idan wa nasiran wa dalilan wa ‘aynan, hatta tuskinahu ardaka taw’an, wa tumatti’ahu fiha tawilan.

O' Allah! Make for Your guard, the proof son of Al-Hasan at this particular time or any other time as as guard, a protector, a leader, a helper, an evidence till You make Your Earth subservient to him, and make him obtain long pleasure in it.
