Ibn Abi Hatim relates: “I heard my father mention this hadith. He said: ‘The wording in question is not reliably preserved; it is one of Ibn Ujlan’s confusions. Kharijah b. Musab also transmitted it—meaning from Zayd b. Aslam—but Kharijah is likewise weak.’” Al-Bayhaqi adds: “Yahya b. al-Ala al-Razi reported it in the same manner, and Yahya b. al-Ala is discarded.” Al-Taqrib describes Yahya as “accused of fabrication,” and of Kharijah it says: “discarded; he practiced tadlis (concealing unreliable sources).” Because the corroboration of these two narrators carries no weight, the report remains unique to Ibn Ujlan. Although he is generally reliable, his memory has been faulted—as Abu Hatim implied—and al-Taqrib states: “Trustworthy, but the hadiths of Abu Hurayrah became mixed up for him.” His narration is therefore classed as hasan (sound) provided it faces no contradiction, yet here it is contradicted: al-Aʿmash transmitted the hadith from Abu Salih without the phrase, “When he recites, keep silent.” This version is recorded by Ibn Majah (1/305) and Ahmad (2/440) with a chain authentic by their standards. Musab b. Muhammad likewise reported it from Abu Salih without the extra words, as cited earlier under the discussion of the takbir. Further chains from Abu Hurayrah—found in al-Bukhari (2/166–172), Muslim (2/19–20), Ibn Majah (1/374), al-Darimi (1/300), and Ahmad (2/230, 214, 411, 438)—also omit this addition.
