The next responsibility is to show honour to the night and day of the 15th of Sha’ban with extra emphasis on the night of the 15th. In addition, one must perform the specific acts which have been recommended to be performed on this night.1
The 15th of Sha’ban is equal in greatness to the night of Qadr (in the month of Ramaďhan), is very important and is one of the time periods related directly to the Imam.
In regards to the greatness of this night, Imam Muhammad b. ‘Ali al-Baqir (as) has stated:
هِيَ أَفْضَلُ لَيْلَةٍ بَعْدَ لَيْلَةِ الْقَدْرِ فِيهَا يَمْنَحُ اللٌّهُ تَعَالَى الْعِبَادَ فَضْلَهُ وَ يَغْفِرُ لَهُمْ بِمَنِّهِ فَاجْتَهِدُوا فِي الْقُرْبَةِ إِلـى اللٌّهِ فِيهَا فَإِنَّهَا لَيْلَةٌ آلَى اللٌّهُ عَلى نَفْسِهِ أَنْ لاَ يَرُدَّ سَائِلاً لَهُ فِيهَا مَا لَمْ يَسْأَلْ مَعْصِيَةً وَ إِنَّهَا اللَّيْلَةُ الَّتِي جَعَلَهَا اللٌّهُ لَنَا أَهْلَ الْبَيْتِ بِإِزَاءِ مَا جَعَلَ لَيْلَةَ الْقَدْرِ لِنَبِيِّنَا فَاجْتَهِدُوا فِي الدُّعَاءِ وَ الثَّنَاءِ عَلى اللٌّهِ
“It (the 15th of Sha’ban) is the best of nights after the night of Qadr. In it Allah grants His blessings to His servants and through His generosity and nobility, He forgives them. So strive and struggle to seek closeness to Allah, the Most High, in it.
For it is a night in which Allah has ordained upon Himself not to turn away anyone who comes to Him asking for something as long as the request is not something impermissible. It is the night which Allah the High, has placed for us (the Ahlul Bayt) just as the Night of Qadr (in the month of Ramaďhan) was placed for our Prophet.
Thus, strive to perform the supplications and praise Allah, the High (in it).”2
The reason for the greatness of this night over all the other nights and times is the felicitous birth of Imam Waliul ‘Asr (ajtf) during the early morning period.
