504 — Al-Firyābī also informed us, saying: Muhammad ibn al-Musaffā narrated to us, saying: Baqiyya ibn al-Walīd narrated to me. He said: I asked Artāh ibn al-Mundhir, saying, “What do you say of someone who denies divine decree?” He replied, “Such a person has not believed in the Quran.” I asked, “What if he interprets it as referring to leprosy and vitiligo ⦗913⦘, being tall or short, and similar things?” He replied, “Such a person has not believed in the Quran.” I asked, “What of his testimony?” He replied, “Once it is established that he is such a person, his testimony is inadmissible, for he is an enemy, and an enemy’s testimony is inadmissible.”
