Abrogation of Recitation a Fact or a Myth

Tradition n. 7

(g) Abu Harb b. Abil Aswad reports from his father:

"Abu Musa Al‑Asha'ri sent for the Qura' (the reciters of Basrah), and three hundred men called upon him, who had all read the Qur’an. Then he said : `You are the best of the people of Basrah, and their reciters. Read the Qur’an constantly, otherwise. before too long, your heart may harden the way the hearts of your predecessors had hardened. We used to read a Surah which we compared, in length and severity, with the Surah of Bara’ah, but I have now forgotten it, except a verse which says:

لو كان لابن آدم واديان من مال لا بتغى واديا ثالثا ولا يملأ جوف ابن آدم الا التراب

And we used to read a Surah which we compared with one of the musabbihat (Surahs which begin with sabbaha or yusab­bihu) but I have forgotten it except a verse I remember7:

يا ايها الذين آمنوا لم تقولون ما لا تفعلون, فتكتب شهادة في اعناقكم فتسألون عنها يوم القيامة
