(In other narrations, He ﷺ mentioned more categories of people who wouldn’t be forgiven, including those who severed the ties of kinship and those who disobeyed their parents, among others).

Aishah (رضي الله عنه) also narrated that the Prophet ﷺ once remained in Sajdah for so long during this night that she became scared, and touched his foot to make sure he was still alive. He ﷺ moved his foot and she heard him reciting the following du’a:

اللَّهُمَّ إِنِّي أَعُوذُ بِرِضَاكَ مِنْ سَخَطِكَ، وَبِمُعَافَاتِكَ مِنْ عُقُوبَتِكَ، وأَعُوذُ بِكَ مِنْكَ، لَا أُحْصِي ثَنَاءً عَلَيْكَ، أَنْتَ كَمَا أَثْنَيْتَ عَلَى نَفْسِكَ

(O Allah, I seek refuge with Your Pleasure from Your anger. I seek refuge in Your forgiveness from Your punishment. I seek refuge in You from You. I cannot count Your praises, You are as You have praised Yourself)

(Note: this du’a is Sahih (authentic) and can be found in Imam Baihaqi’s collection, among others. It is narrated that the Prophet (saw) used to recite it during Sujood and after Witr prayer. It being recited on 15th Sha’ban is considered acceptable by scholars)

The Prophet ﷺ also said to Aishah (رضي الله عنه): "Allah descends on the night of the middle of Sha’ban to the lowest heaven, and He forgives more than the numbers of hairs on the sheep of Banu Kalb (an Arab tribe renowned for their great flocks of sheep)". [Ibn Majah and others]

Finally, the Prophet ﷺ said that on this night, from sunset until dawn, Allah asks His servants, "Is there anyone seeking forgiveness from Me so that I may forgive him? Is there anyone seeking provision from Me so I may provide for him? Is there anyone suffering so I may relieve his suffering?". [Ibn Majah]
