Ardaas is a prayer of the Sikhs. In this app ardaas is available in Hindi, English and Gurmukhi languages and also available in audio version.
The Ardās (Punjabi: ਅਰਦਾਸ) is a set prayer in Sikhism. It is a part of worship service in a Gurdwara (Sikh temple), daily rituals such as the opening the Guru Granth Sahib for prakash (morning light) or closing it for sukhasan (night bedroom) in larger Gurdwaras, closing of congregational worship in smaller Gurdwaras, rites-of-passages such as with the naming of child or the cremation of a loved one, daily prayer by devout Sikhs and any significant Sikh ceremonies.

The Ardās is usually always done standing up with folded hands and is commonly preceded by the eighth stanza of the fourth ashtapadi of the bani 'Sukhmani Sahib', beginning Tu Thakur Tum Peh Ardaas. The beginning of the Ardas is strictly set by the tenth Sikh Guru, Guru Gobind Singh and may not be altered or omitted. It appears as the opening passage of Var Sri Bhagauti Ji Ki (see Chandi di Var) and is an invocation to God and reminder of the Sikh Gurus.

An Ardas consists of three parts. The first part recites the virtues of the ten Gurus of Sikhism from Guru Nanak to Guru Gobind Singh, starting with lines from Chandi di Var from the Dasam Granth. The second part recites the trials and triumphs of the Khalsa and petition. The third salutes the divine name. The first and the third part are set and cannot be changed, while the second part may vary, be shortened and include a supplication such as seeking divine help or blessing in dealing with daily problems, but is usually in agreed form. While it is sung, the audience or the Sikh devotee typically stands, with hands clasped in the folded namaste gesture, many with bowed headed, with some typically saying "Waheguru" after certain sections.

Ardas is attributed to Guru Gobind Singh, the founder of the Khalsa and the 10th Guru of Sikhism.
