*81). Jibt signifies 'a thing devoid of any true basis and bereft of all usefulness'. In Islamic terminology the various forms of sorcery, divination and soothsaying, in short all superstitions, are termed jibt. It is reported in a tradition that, 'to divine things from the cries of animals, or the traces of animals' paws, or the flight of birds, constitutes jibt. Thus, jibt may be roughly translated as 'superstition'. (See Abu Da'ud, Tibb', 23; Ahmad b. Hanbal, Musnad, vol. 3, p. 477 and vol. 5, p. 60 - Ed.)
*82). For explanation see Towards Understanding the Qur'an, vol. I, Surah 2, nn. 286 and 288.
*83). The obstinacy of the Jewish religious scholars had, reached such a point that they brazenly declared the followers of Muhammad (peace be on him) to be in greater error than even the polytheists of Arabia. This was despite the fact that they knew that the Muslims stood for absolute monotheism while their opponents believed in that undisguised polytheism which has been so vehemently denounced throughout the Bible.
