 Prayer in the night of 15th Shaban 

 On the night of 15th Shaban it is recommended to say the following prayer, which is like a Ziyarat for Imam al-Mahdi(a.s.). This prayer has been mentioned by both Sayyid Ibn Tawus and Shaykh al-Tusi:

 اللّٰهُمَّ بِحَقِّ لَيْلَتِنَا [هَذِهِ‏] وَ مَوْلُودِهَا وَ حُجَّتِكَ وَ مَوْعُودِهَا الَّتِي قَرَنْتَ اِلَى 

 O ALLAH! For the sake of this night and the one who is born in that and Your Hujjat and the promised one upon whom You bestowed Blessings upon Blessings.

 فَضْلِهَا فَضْلا فَتَمَّتْ كَلِمَتُكَ صِدْقا وَ عَدْلا لا مُبَدِّلَ لِكَلِمَاتِكَ وَ 

Hence Your Words completed with truth and justice, the Words that cannot be changed.

 لا مُعَقِّبَ لِآيَاتِكَ نُورُكَ الْمُتَاَلِّقُ وَ ضِيَاؤُكَ الْمُشْرِقُ وَ الْعَلَمُ النُّورُ فِي طَخْيَاء 

Your verses cannot be changed. He is Your shining Light and Your Light in Florescence. He is the beacon of Light in the darkness of night,

 الدَّيْجُورِ الْغَائِبُ الْمَسْتُورُ جَلَّ مَوْلِدُهُ وَ كَرُمَ مَحْتِدُهُ وَ الْمَلائِكَةُ 

Hidden in the absence. His birthplace is Glorified, his origin is dignified and angels are 

 شُهَّدُهُ وَ اللّٰهُ نَاصِرُهُ وَ مُؤَيِّدُهُ اِذَا آنَ مِيعَادُهُ وَ الْمَلائِكَةُ [فَالْمَلائِكَةُ]

 He is the Sword of Allah that does not loose its sharpness and Light that does not extinguish. He possesses the forbearance that does not leave the limits.

 لا يَصْبُو مَدَارُ الدَّهْرِ وَ نَوَامِيسُ الْعَصْرِ وَ وُلاةُ الْاَمْرِ وَ الْمُنَزَّلُ عَلَيْهِمْ مَا

 اَنْصَارِهِ وَ اقْرِنْ ثَارَنَا بِثَارِهِ وَ اكْتُبْنَا فِي اَعْوَانِهِ وَ خُلَصَائِهِ وَ اَحْيِنَا فِي دَوْلَتِهِ
