There is no doubt that this commentary is not the work of Ibn ʿAbbas. The chain of transmitters of this commentary goes back to Muḥammad ibn Marwān -> al-Kalbi -> Abū Ṣāliḥ which is described by Hadith experts as the chain of lies (silsilat al-kadhib), for this line of transmission is utterly dubious and unreliable. One does not even need to use the criteria for reliable transmission applied by Hadith experts to decide this commentary’s wrong attribution to ibn ʿAbbas. It is easy to detect obvious anomalies in the text of Tanwir al-Miqbas which leave one with no doubt that whoever wrote it lived many centuries after ibn ʿAbbas. One finds it, for instance, references to Hasan al-Basri, aṣ-Ṣuddi and even the grammarian Yaḥya ibn Ziyād al Farraʾ(d. 207/822).6 In a few places, after giving different meanings of the same verse, the author(s) or compiler(s) proceed(s) to say: “… and this is the opinion of ibn ʿAbbas” or: “ibn ʿAbbas says…”, forgetting that the entire commentary is supposed to be an accurate transmission of what is narrated from ibn ʿAbbas.
