15 th Shabaan,which is popularly known as 'Shabb-e-Baraa't' in the Indian sub-continent

In the name of Allah
Shabaan is the eight-month of the Islamic calendar. Allah's Messenger (sallallahu alaihi wa-sallam) used to spend most part of Shabaan by fasting...
Some ignorant people have themselves specified particular nights of the year, when they stay awake all night and worship Allah. It is believed that anyone who worships Allah in these specific nights, it will recompense for his yearly deeds and will be enough for his salvation and entering Jannah. One among these nights is the night of mid Shabaan(15thShabaan),which is popularly known as 'Shabb-e-Baraa't' in the Indian sub-continent.
Hadith on shab-e-baraat
In the name of Allah, We praise Him, seek His help and ask for His forgiveness. Whoever Allah guides none can misguide, and whoever He allows to fall astray, none can guide them aright. We bear witness that there is no one (no idol, no person, no grave, no prophet, no imam, no dai, nobody!) worthy of worship but Allah Alone, and we bear witness that Muhammad(saws) is His slave-servant and the seal of His Messengers.
There is indeed an hadith regarding the statement of the Messenger of Allah (saws), which is narrated by Hadrat Aisha (r.a.); but Tirmidhi who is the relater of the hadith declared it himself that Bukhari deemed it to be a weak hadith!
Al-Tirmidhi Hadith 1299 Narrated by Aisha
I missed Allah's Messenger (saws) during the night and found him in al-Baqi'. He (saws) said: “Were you afraid that Allah and His Messenger would deal unjustly with you?” I said: “O Allah's Messenger (saws), I thought that you had gone to some of your other wives.” The Prophet(saws) said: “Verily Allah, the Exalted and Glorious, comes down to the heaven of the world in the middle night of Sha'ban and forgives sins even more abundant than the hair of the goats of Kalb.” Reported by Tirmidhi, Ibn Majah, and Razin, and Tirmidhi said: I heard it from Muhammad (Bukhari) that he deemed it to be a weak hadith.
But there is absolutely no evidence or basis in the Glorious Quran or any of the authentic reports of Sunnah for the following claims:
It is the second most important night in the Islamic year after Lail latul Qadar
It is a night Allah swt bestows rahmat, forgiveness and rizq
For many it is night of Qiyamul lail.
We humbly request the brother who has claimed that “there are many authentic hadiths on this” to please produce his evidence to justify his claims, if he is indeed speaking the Truth!; for it is indeed a grave sin in the sight of the Lord to attribute something falsely to the Messenger of Allah (saws)!
Sahih Al-Bukhari Hadith 1.106 Narrated by Hadrat Ali ibn Abi Taalib (r.a.)
The Prophet (saws) said, "Do not tell a lie against me, for whoever tells a lie against me (intentionally) then he will surely enter the Hell-fire."
Sahih Al-Bukhari Hadith 1.109 Narrated by Salama
I heard the Prophet (saws) saying, "Whoever (intentionally) ascribes to me what I have not said, then (surely) let him occupy his seat in Hell-fire."
As far as visiting the graves is concerned, a weak narration (of Aaishah (radhi allahu anha) reported in Sunan at-Tirmidhee (in the book of fasting) is often brought forth to support the visiting of graves on the night of 15th Shabaan. The Hadeeth reads as follows, One night (i.e. night of mid Sh'abaan) I found the Messenger of Allah absent from my apartment. I therefore, went out to search him out and he was in Baqi raising his head towards the heaven.' He said, “O Aa’ishah were you afraid that Allah and His Messenger will wrong with you?” She said, 'I replied: I had not such a low opinion about Allah and His Messenger, but I presumed that you had gone to some of your wives for some need." He said, “Verily, Allah descends in the night of mid-Shabaan to the heaven of the world and then forgives people more than the number of the hair of the sheep of Banu Kalb.” A similar Hadeeth is also found in Saheeh Muslim, but it does not mention the night of 15th Shabaan. However, the Hadeeth of Sunan at-Tirmidhee is not authentic and thus does not have any proof for visiting graves specifically on the night of Shabaan.
Allah's Messenger (sallallahu alaihi wa-sallam) has permitted the men to visit the graves at any time and make Du'aa for the engraved. He (sallallahu alaihi wa-sallam) said, “I used to forbid you from visiting graves, but now you should visit them, for surely they are reminders of the next life.” [Saheeh Muslim (2131)] And he (sallallahu alaihi wa-sallam) also taught us the Du'aa of visiting graves, “Peace be upon the Believers and Muslims among the inhabitants of these dwellings. May Allah have mercy on those who have gone ahead of us, and those following us. And we shall, Allah-willing, be joining you.” [Saheeh Muslim (2127)] But to specify certain days for visiting graves was neither the practice of Allah's Messenger (sallallahu alaihi wa-sallam), nor the Sahabah (radhi allahu anhu) therefore, visiting graves specifically on 15th Shabaan should be avoided, as it falls under the category of innovations and Allah's Messenger (sallallahu alaihi wa-sallam) said about innovations, “…the worst of affairs are the newly invented matters, every newly invented matter is an innovation and every innovation is misguidance and every misguidance is in the Hell-Fire.” [An-Nasa'ee]
Many people also light candles on graves, which has no basis from the Qur'aan and the Sunnah. In fact, lighting candles is an imitation of the fire-worshipers and Ibn Abbas (radhi allahu anhu) narrated that Allah's Messenger (sallallahu alaihi wa-sallam) cursed the women who visit the graves. He also cursed those who set up mosques and lights over graves.” [(Hasan) Abu Dawood, Ibn Majah, at-Tirmidhee and an-Nas'aee]
Whatever written of Truth and benefit is only due to Allah’s Assistance and Guidance, and whatever of error is of me alone. Allah Alone Knows Best and He is the Only Source of Strength.
