Though popularly known as Aad Granth, the
Proper Name of This Holy collection of Gurbanis is:
The Aad Gurus whose Banis are written in Aad Sri Guru Granth Sahib are:
Guru Nanak Dev Ji: 947 Banis in 19 Ragas.
Guru Angad Dev Ji: 63 Sloks.
Guru Amardas Ji: 869 Banis in 17 Ragas.
Guru Ramdas Ji: 638 Banis in 30 Ragas.
Guru Arjan Dev Ji: 2312 Banis in 30 Ragas.
Guru Tegbahader Sahib Ji: 115 Banis.
But Guru Sahib, Sri Guru Arjan Dev Ji, also gave place for Banis of Bhagats such as Kabir Ji, Farid Ji, Ravdas Ji, and many more in this Granth.
Though the compilation was done during the times of Sri Guru Arjan Dev Ji, the Banis of Sri Guru Tegbahader Sahib was added by the contemporary Sikhs of the time. About five years before The Ninth Master's Martyrdom, as the evidents suggest, The Sikhs were known to be adding His Banis to their original copies of Aad Granth Sahib and obtaining His Holiness's Signatures on them.
It was not until Sri Guru Gobind Singh Ji sat on the throne of Gurudom that all of the Ninth Master's Banis were added, at Sri Anandpur Sahib before the creation of Khalsa, and the Granth was transformed into its present form.
However, the journey of Aad Granth Sahib did not end there. After the enlgishmen entered into India buying the rich and killing the poor, religious righteousness did not matter anymore and The Granth Sahibs were kept away on shelves totally forgotten for their existence.
It was only after Sri Satguru Ram Singh Ji's Re-Creation of The Khalsa in 1857 that He traveled through Punjab, put people back on the right tracks and reopened the Dharamsalas(house of worships) that were locked for years, cleaned the volumes of Aad Granth Sahibs that were covered with dust using His Dastar(turban), and Taught the Sikhs the kind of respect and regard they should have towards Gurbani.
Only then, was the Holy Granth rediscovered and its status restored to what it is, a Holy Collection of Guru's Words.
-*In the Aad Granth Sahib, The following verse has been changed by Guru Gobind Singh Ji:
However, the change took place when Guruji were at war, therefore it was not recorded in the Granth. Nevertheless The Sikhs are Instructed to read The Verse in the form as changed by The Tenth Lord.*-
