Guru Arjan was the first of the two Gurus martyred in the Sikh faith and the fifth of the ten total Sikh Gurus. He compiled the first official edition of the Sikh scripture called the Adi Granth, which later expanded into the Guru Granth Sahib. He was born in Goindval, in the Punjab, the youngest son of Bhai Jetha, who later became Guru Ram Das, and Mata Bhani, the daughter of Guru Amar Das. He completed the construction of Darbar Sahib at Amritsar, after the fourth Sikh Guru founded the town and built a sarovar. Guru Arjan compiled the hymns of previous Gurus and of other saints into Adi Granth, the first edition of the Sikh scripture, and installed it in the Harimandir Sahib. Guru Arjan reorganized the Masands system initiated by Guru Ram Das, by suggesting that the Sikhs donate, if possible, one-tenth of their income, goods or service to the Sikh organization . The Masand not only collected these funds but also taught tenets of Sikhism and settled civil disputes in their region. The dasvand financed the building of gurdwaras and langars (shared communal kitchens). Guru Arjan was arrested under the orders of the Mughal Emperor Jahangir accusing him of supporting a rebellion under Khusrau Mirza. He was asked to convert to Islam. He refused, was tortured and executed in 1606 CE. Historical records and the Sikh tradition are unclear as to whether Guru Arjan was executed by drowning or died during torture. The Sikh tradition states the Guru's execution was a part of the ongoing persecution of the Sikhs under the Mughal Empire. His martyrdom is considered a watershed event in the history of Sikhism. It is remembered as Shaheedi Divas of Guru Arjan in May or June accordi
