WAJAB UL-ARZ, lit. a properly petition, is a section of Sikhan di Bhagat Mala, also known as Gursikkhan di Bhagatmal, a manuscript in Punjabi, Gurmukhi script, attributed to Bhai Mani Singh (d. 1737) the martyr, who had received the rites of initiation at the hands of Guru Gobind Singh himself. Three copies of the manuscript were preserved in the Sikh Reference Library at Amritsar under No. 7398, No. 6140 and No. 751 until these perished during operation Blue Star in 1984. The printed version of Sikhan di Bhagat Mala however does not include this section. The Wajab ul-Arz also forms part of Bhagvan Singh\'s anthology of rahitnamas entitled Bibekbardhi, an unpublished manuscript of which is preserved in the Dr Balbir Singh Sahitya Kendra, Dehra Dun.
ZAIN KHAN (d. 1764), an Afghan, was appointed governor of Sirhind in March 1761 by Ahmad Shah Durrani. Earlier he had acted as Faujdar of Char Mahal the four districts of Sialkot, Gujrat, Pasrur and Aurarigabad. This was from 1759 when Karim Dad Khan was appointed governor of the Punjab by the Afghan invader. For his relentless campaign against the Sikhs and for his part in die Vadda Ghallughara ( 5 February 1762), or Great Carnage, at the village of Kup Rahira near Malerkotia, Zain Khan had become a special target of their vengeance. Within four months of the Ghallughara they attacked Sirhind with a strong force, inflicting upon him a severe defeat and laying him under tribute.
AFGHAN SIKH RELATIONS spanning the years 1748 to 1849 go back to the first invasion of India by Ahmad Shah Durrani, although he must have heard of the Sikhs when in 1739 he accompanied Nadir Shah, the Iranian invader, as a young staff officer. Having occupied Lahore after a minor engagement fought on 11 January 1748 during his first invasion of India, Ahmad Shah advanced towards Sirhind to meet a Mughal army which he was informed was advancing from Delhi to oppose him. On the way he had two slight skirmishes at Sarai Nur Din and at the Vairoval ferry, both in present day Amritsar district, with a Sikh jatha or fighting band under Jassa Singh Ahluvalia.
