Jaap is the bani uttered by Guru Gobind Singh ji, the Tenth Sikh Guru, the Tenth Nanak. It is one of the Five Banis recited by most practising Sikhs each morning and the bani that the Panj Pyare recite while preparing Amrit on the occasion of Amrit Sanchaar (Sikh Initiation), a ceremony held to admit initiates into the Khalsa Brotherhood. It is the second bani of the five in the daily morning prayer routine of a Sikh.
This bani has the same place in the Dasam Granth as the Japji Sahib has in Guru Granth Sahib.
Guru Gobind Singh was a worshipper of one God (Akal) this is proved by the first stanza of Jaap sahib. Guru Gobind Singh ji completed this bani before 1699, because this bani was recited during the installation of the khalsa. Professor Sahib Singh says that, " Guru Gobind SIngh went to Nahan in 1684 and lived there for approximately 3 years. During these three years guru Sahib may have composed the Jaap Sahib, the Swaiyey and the Akal Ustat.
