It is narrated by Hazrat Ali Murtaza (may Allah be pleased with him) that the Holy Prophet of Allah (Peace Be Upon Him – 
) said when the 15th of Sha`ban arrives you should do qayyam (stay awake) i.e. read voluntary prayer and keep fast in the day because Allah (glory be to Him) descends to the worldly sky on this night after the setting of the sun, and says thus:
“Is there anyone who seeks forgiveness that I may forgive him?”
“Is there anyone who wants provision that I may give him provision?”
“Is there anyone in tribulation that I may free him of his tribulation?”
and Allah keeps saying like this till the sunrise.
It is narrated by Hazrat Abu Hurrairah (may Allah be pleased with him) that the Holy Prophet (Peace Be Upon Him – ) said that Hazrat Arch Angel Gabriel (may Allah be pleased with him) came to Me (Peace Be Upon Him – ) at night on the 15th of Sha`ban and said to Me (Peace Be Upon Him – ).
“Oh the Messenger of Allah Muhammad (Peace Be Upon Him –
The Holy Prophet (Peace Be Upon Him – ) said that I (Peace Be Upon Him – ) inquired from him as to what night was this? Hazrat Arch Angel Gabriel said
“This is one night in which Allah opens 300 doors from the doors of mercy. So He forgives everyone who does not associate Allah with anything and except the one who is a wizard or deals in witchcraft or is a forever alcohol drinker or is persistant in taking interest or is persistant in adultery. Thus such people will not be forgiven until they repent.”
When the forth part of the night passed Hazrat Arch Angel Gabriel (may Allah be pleased with him) descended again and said
“Oh the Messenger of Allah Muhammad (Peace Be Upon Him –
Thus I (Peace Be Upon Him – ) raised my head and found the doors of the heaven open and the angel at the first door calls out
“Glad tidings to the one who bows down during this night.”
and the angel at the second door calls out
“glad tidings to the one who prostrates during this night”
and the angel at the third door says
“glad tidings to the one who supplicates (makes a dua) during this night”
and the angel at the fourth door calls out
“glad tidings to the ones doing zikr (remembrance of Allah) during this night”
and the angel at the fifth door calls out
“glad tidings to the one who cries from the fear of Allah during this night”
and the angel at the sixth door calls out
“glad tidings to the believers on this night”
and the angel at the seventh door calls out
“Is there anyone who has a need that his need may be fulfilled”
and the angel at the eighth door calls out
“Is there anyone who seeks forgiveness that he may be forgiven.”
Thus I (Peace Be Upon Him – ) inquired oh Gabriel when will these doors be open till? Arch Angel Gabriel (may Allah be pleased with him) replied till the sunrise and started from the begining of night and he continued oh the messenger of Allah Muhammad (Peace Be Upon Him – ),
“Allah (glory be to Him) during this night has freed (people) from fire according to the number of hair on the goats of (Bani) Kalb.”
On the 15th of Sha`ban Read 100 Rakats of Salat ul Khair and read 1000 Surah Ikhlas in these rakats i.e. read 10 Surah Ikhlas in each rakat.
Salf Salaheen (may Allah be pleased with them all) used to get together to pray Salat ul Khair in congregation.
Hazrat Hassan Basry (may Allah be pleased with him) has said that
“Thirty(30) Companions (may Allah be pleased with them all) of the Holy Prophet Muhammad (Peace Be Upon Him –
Whoever in the month of Sha`ban reads 11 times Surah Ikhlas and blesses the reward of this on the soul of Hazrat Sayyaditun Nisa Hazrat Fatimah Zuhrah (may Allah be pleased with her). Hazrat Sayyaditun Nisa Hazrat Fatimah Zuhrah (may Allah be pleased with her) says that she will not enter paradise until she doesn’t get intercession for that person.
