Q: Im actually confused, I had read That link before nly, we usally offer 6 nafils n salatut tasbi n keep doing zikr on dat nite (15th of Sha'baan). Is doing this is also bidah..

A; All-Praise is due to Allah,
It is a general ruling in Sharia anything that has not been prescribed by Allah & His Messenger (pbuh) has no room for practicing it or to associate it to Sharia. Allah The All-Mighty said in a verse closely translated to the meaning, 'Verily It is We Who have sent down the Dhikr (i.e. the Qur'an & Sunnah) and surely, We will guard it (from corruption).' (15/9)
And He the Exalted said, 'O people of the Scripture! Do not exceed the limits in your religion, nor say of Allah aught but the truth.' (4/171)
The Prophet (pbuh) said, "If somebody innovates something which is not in harmony with the principles of our religion, that thing is rejected." (Bukhari, Volume 3, Book 49, Number 861)
This Hadith that has been mentioned by the Prophet (pbuh) is a Fundamental Principle of Sharia' that is used by Scholars to derive what is considered an innovation. As what you have mentioned there is know bases for it according to the Sharia', There for there is no reason to specify and relate it to part of the religion when it has not been related by Allah and His Messenger. In a sound Hadith related by Abu Dawood, The Prophet (pbuh) said, 'I enjoin you to fear Allah, and to hear and obey even if it be an Abyssinian slave, for those of you who live after me will see great disagreement. You must then follow my Sunnah and that of the rightly-guided caliphs. Hold to it and stick fast to it. Avoid novelties, for every novelty is an innovation, and every innovation is an error' & in another narration that is added onto the end of this Hadith, for every novelty is an innovation, and every innovation is an error, and every error is in the hellfire….
The words of the Prophet (pbuh) are quite clear, take what is only authentically narrated by the Prophet (pbuh) and beware of weak and fabricated Hadiths, especially innovated acts that have been widely spread through out several of the Muslim lands around the world. I leave you with the saying of one of the most famous Hadith Narraters Sufyan Ath-Thawri who once quoted, 'Bidah (innovation) is more beloved to satan then sin'
And Allah knows best….
