✅ In addition to the general deeds of the month of Sha'ban, please pay attention to the following two narrations:

1 عَنْ عَبْدِ السَّلَامِ بْنِ صَالِحٍ الْهَرَوِيِّ قَالَ: دَخَلْتُ عَلَى أَبِي الْحَسَنِ عَلِيِّ بْنِ مُوسَى الرِّضَا فِي آخِرِ جُمُعَةٍ مِنْ شَعْبَانَ فَقَالَ لِي يَا أَبَا الصَّلْتِ إِنَّ شَعْبَانَ قَدْ مَضَى أَكْثَرُهُ وَ هَذَا آخِرُ جُمُعَةٍ مِنْهُ فَتَدَارَكْ فِيمَا بَقِيَ مِنْهُ تَقْصِيرَكَ فِيمَا مَضَى مِنْهُ وَ عَلَيْكَ بِالْإِقْبَالِ عَلَى مَا يَعْنِيكَ وَ تَرْكِ مَا لَا يَعْنِيكَ وَ أَكْثِرْ مِنَ الدُّعَاءِ وَ الِاسْتِغْفَارِ وَ تِلَاوَةِ الْقُرْآنِ وَ تُبْ إِلَى اللَّهِ مِنْ ذُنُوبِكَ لِيُقْبِلَ شَهْرُ اللَّهِ إِلَيْكَ وَ أَنْتَ مُخْلِصٌ لِلَّهِ عَزَّ وَ جَلَّ وَ لَا تَدَعَنَّ أَمَانَةً فِي عُنُقِكَ إِلَّا أَدَّيْتَهَا وَ لَا فِي قَلْبِكَ حِقْداً عَلَى مُؤْمِنٍ إِلَّا نَزَعْتَهُ وَ لَا ذَنْباً أَنْتَ مُرْتَكِبُهُ إِلَّا أَقْلَعْتَ عَنْهُ وَ اتَّقِ اللَّهَ وَ تَوَكَّلْ عَلَيْهِ فِي سَرِّ أَمْرکَ وَ عَلَانِيَتِكَ وَ مَنْ يَتَوَكَّلْ عَلَى اللَّهِ فَهُوَ حَسْبُهُ إِنَّ اللَّهَ بالِغُ أَمْرِهِ قَدْ جَعَلَ اللَّهُ لِكُلِّ شَيْ ءٍ قَدْراً وَ أَكْثِرْ مِنْ أَنْ تَقُولَ فِيمَا بَقِيَ مِنْ هَذَا الشَّهْرِ اللَّهُمَّ إِنْ لَمْ تَكُنْ غَفَرْتَ لَنَا فِيمَا مَضَى مِنْ شَعْبَانَ- فَاغْفِرْ لَنَا فِيمَا بَقِيَ مِنْهُ- فَإِنَّ اللَّهَ تَبَارَكَ وَ تَعَالَى يُعْتِقُ فِي هَذَا الشَّهْرِ رِقَاباً مِنَ النَّارِ لِحُرْمَةِ شَهْرِ رَمَضَانَ.

📚 Uyun Akhbar al-Ridha (peace be upon him) Vol. 2, p. 51

Abd al-Salam said: I entered upon Imam al-Ridha (peace be upon him) in the last week of the month of Sha'ban. The Imam said to me: O Aba Salt! Most of the month of Sha'ban has passed and this is its last week, so in what remains of it, make up for your shortcomings and negligence in its past. And it is upon you to turn to what you need and leave what you do not need, and increase your supplication, seeking forgiveness, and recitation of the Quran, and repent from your sins to Allah, so that the month of Allah (i.e., the month of Ramadan) comes to you while you are sincere for Allah the Almighty. And never leave any trust that is on your neck unless you deliver it (to its owner), and do not leave any grudge in your heart against a believer unless you remove it, and no sin that you have committed unless you detach and separate yourself from it. And fear Allah and put your trust in Him in your hidden and manifest affairs, and whoever trusts in Allah, then He is sufficient for him. Indeed, Allah is the one who brings His command to pass, and He has set a measure for everything. And in the remainder of this month, say a lot:

اللَّهُمَّ إِنْ لَمْ تَكُنْ غَفَرْتَ لَنَا فِيمَا مَضَى مِنْ شَعْبَانَ فَاغْفِرْ لَنَا فِيمَا بَقِيَ مِنْهُ

Meaning: O Allah! If You have not forgiven us in the past of the month of Sha'ban, then forgive us in what remains of it!

For Allah, the Blessed and Exalted, in this month frees necks from the fire of hell in honor of the month of Ramadan!

2 عَنِ الْمُفَضَّلِ بْنِ عُمَرَ عَنِ الصَّادِقِ جَعْفَرِ بْنِ مُحَمَّدٍ قَالَ: مَنْ صَامَ ثَلَاثَةَ أَيَّامٍ مِنْ آخِرِ شَعْبَانَ وَ وَصَلَهَا بِشَهْرِ رَمَضَانَ كَتَبَ اللَّهُ لَهُ صَوْمَ شَهْرَيْنِ مُتَتَابِعَيْنِ.

📚 Amali Al-Saduq p. 533, hadith 8

Imam al-Sadiq (peace be upon him) said: Whoever fasts the last three days of the month of Sha'ban and connects it to the month of Ramadan, Allah will write for him the fasting of two consecutive months!

اللَّهُمَّ فَصَلِّ عَلَی مُحَمَّدٍ وَ آلِ مُحَمَّدٍ وَ عَجِّلْ لِوَلِیِّکَ الْفَرَجَ وَ الْعَافِیَةَ وَ النَّصْرَ
