Khafi Khan's Muntakhab-al Lubab has been a much studied text in the modern era. It covers events up to the beginning of the 14th year of Muhmmad Shah's reign, that is, about 1731–1732. According to M. Athar Ali, the manuscripts of Khafi Khan's works discovered later and the manuscripts of other Mughal era historians shows that this book incorporates without acknowledgmen the work of other Muslim authors with pen names Sadiq Khan and Abu'l Fazl Ma'muri on emperors Shah Jahan and Aurangzeb, in a manner that would be "regarded as gross plagiarism" in modern era scholarship. The identity of the original authors behind the pen names is not known and their credibility is difficult to gauge.
