> For the historians, difficulties have been created because the execution of Guru Tegh Bahadur in Delhi in 1675 is not mentioned in any of the contemporary Persian sources. Nor are there any Sikh contemporary accounts,
The books that mention this event are based on the testimony of some Sikhs.
> those written towards the end of the 18th century depending on ``the testimony of trustworthy Sikhs''. They are, therefore, often conflicting.
The earliest written account of this event was written more than 100 years after it happened.
> The earliest account of the events leading to the Guru's execution is in Siyar-ul- Mutakharm by Ghulam Husain Taba- Tabai in 1780, more than 100 years afterwards.
