15 Sha'ban - Laylatul Bara'a
The 13th, 14th and 15th of Rajab, Sha'ban and Ramadan are known as “Ayyamul Biydh” which are known as the “Days of Passing Splendour” or “Bright Days”.
The Prophet (pbuh) had said that during the nights of the 15th Sha'ban, the Almighty takes decisions in the matters of sustenance, life, death and the welfare of the people.
Rasulullah (pbuh) has also said: "When the night of the middle of Sha’ban comes, spend the night in prayer and fast the next day for in it Allah forgives more sins than the hairs of the goats of the tribe of Kalb."
He also said: " When the night of the middle of Sha’ban comes, Allah says: "Is there anyone begging for forgiveness that I might forgive him? Is there anyone begging for sustenance that I may feed him? Is there any such and such?"
Next to the “Night of Qadr”, the 15th Sha'ban is the most auspicious night (also known as the “Night of Bara'a”). According to Imam Muhammad Al-Baqir (pbuh) and Imam Jafar As-Sadiq (pbuh), Allah has promised to fulfil every legitimate desire put forward to Him in that night. Imam As-Sadiq (pbuh) has said: “Whoso prays during the nights of “Ayyam Biydh”, in fact, stands at the door of the superabundant favours, bounties and benefits available in these months.”
It is highly desirable to fast on the 13th, 14th and 15th, do ghusl and give sadaqa. Pray a 12 Rak’at salaa as follows: In the night of the 13th, pray 12 Rak’ats in sets of 2 and recite Suratul Fatiha, Suratu Yaseen and Suratul Mulk in each Rak’at. In the night of the 14th, pray 4 Rak’ats in 2 sets of 2 Rak’at, and recite Suratul Fatiha, Suratu Yaseen and Suratul Mulk in each Rak’at.
In the night of the 15th, pray 6 Rak’ats in 3 sets of 2 Rak’ats and recite Suratul Fatiha, Suratu Yaseen and Suratul Mulk in each Rak’at.
