It is narrated from Abu Wa'il; he said that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) used often to recite this verse in this way: "Indeed, this Qur'an guides to that which is most upright and gives good tidings to the believers" (and he would read «yubashshiru» light, without doubling, that is «yabshuru»). Uthman (the narrator) said: And this is the reading of Hamzah. The chain of this hadith is sahih (authentic), and the two Shaykhs did not record it.
