Prophet (صلی اللہ علیہ وسلم) said that the month of Shaban is a very glorious month and Allah Almighty also rewards everyone extensively.

Nafli Namaz:
In the month of Shaban on the first night after praying the Isha Namaz pray 12 rakat namaz with the action of salam 6 times. In each rakat after reciting surah Fatiha recite surah Ikhlas 15 times. After saying the salam recite the durud-e-pak 70 times and ask forgiveness for your sins. Inshallah Allah Almighty will support and forgive you and allow you to enter heaven. 
In this month on the first night of Friday after praying the Isha Namaz pray 8 rakat namaz with the action of salam once and in each rakat after reciting surah Fatiha recite surah Ikhlas 11 times and intend its rewards for Hazrat Fatimah (رضی اللہ عنہا). She said that I will never step into the heaven until those who pray this namaz enter into the heaven with me. In the month of Shaban on the first night of Friday prayer after praying the Isha Namaz pray four rakat namaz with the action of salam once and in each rakat after reciting surah Fatiha recite surah Ikhlas three times. Allah Almighty will award this person with the gift of Umrah. 

On the first day of Friday of Shaban after praying the Maghrib prayer and Isha prayer, pray two rakat namaz. In each rakat after reciting surah Fatiha recite Ayat-ul-Kursi once, surah Ikhlas 10 times, surah Falaq once and surah Nas once. Inshallah Allah Almighty will grant you success and faith. 

Wazifa:
On the 14th of Shaban-ul-Mauzam after praying the Asr namaz before the setting of the sun recite the following verses 40 times  

Allah Almighty will forgive those who pray this dua for their 40 years of sins. (Inshallah)

Announcement of forgiveness:

Hazrat Prophet (صلی اللہ علیہ وسلم) said that on the 15th night of Shaban-ul-Mauzam the worship of Allah Almighty is the best. On this night, Allah Almighty opens many doors of blessing and asks who is it that pleads for my support and I shall make him safe from the fire of hell and forgive him. Prophet (ﷺ) said that whoever does this worship, the fire of hell will be forbidden upon him.

Nowafl and fast:
It is heard from Hazrat Ali (رضی اللہ عنہ   ) that Prophet (ﷺ) said that on the 15th night of Shaban you should do qiyam meaning he should pray nowafl and keep fast in the day. On this night Allah asks if there is anyone who wishes to be blessed and I shall bless him, if there is anyone who needs support and stability and I shall provide it for him, if anyone is stuck in a difficult situation and I shall help him.

Shab-e-barat:

On this night the Salah Khair namaz should be prayed. Hazrat Khoba Hassan (رضی اللہ عنہ   ) said that I was told by 30 followers of the Prophet (ﷺ) that on this night if anyone prays this namaz Allah Almighty looks at him 70 times and fulfills 70 needs of the person in each glance the most important being the forgiveness of sins. In this prayer you are required to pray 100 rakats in 2 pairs each. In every rakat the surah Ikhlas must be recited 10 times. After completion of the namaz, you must pray. (Worship at night and keep fast in the day).

On this night pray two rakat namaz in such a way that after reciting surah Fatiha recite Ayat-ul-Kursi once, surah Ikhlas 15 times and after the action of salam recite darood shareef 100 times and pray for successful provision of necessities of life. Inshallah Allah Almighty will accept your prayer. Anyone who prays an eight rakat namaz with the action of salam two times and in each rakat after reciting surah Fatiha recite surah Ikhlas ten times Allah Almighty will send several angels to protect him from the agony in the grave and to give him the good news of entering the heaven. 

The blessings of Hajj and Umrah while sitting at home:
In the month of Shaban on every Friday night pray four rakat namaz. In each rakat after reciting surah Fatiha recite surah Ikhlas three times. Whoever does this will gain the blessings equal to those obtained by Hajj or Umrah.
