Upon this narration, there is no derivation. However, upon the other [narration], it is necessary to specify what he will teach her, either a specific surah, or [several] surahs, or specific verses; because surahs differ, as do verses. Is it necessary to specify whose recitation (34) it is? There are two views: one of them is that it is necessary, because intentions vary and recitations differ; some are difficult, like the recitation of Hamzah, and some are easy, so it resembles specifying verses. The second view is that it does not require specification, because this is a minor difference, where every letter substitutes for the other and stands in its place; for this reason, the Prophet (peace and blessings of Allah be upon him) did not specify a recitation to the woman, even though they differed in recitation more than the reciters do today, so it resembles the case where he gives her a qafiz of wheat from a pile. Al-Shafi'i has two views on this, similar to these two.

Section: If he gives her as a dowry the teaching of a surah that he does not know how to recite, consider: if he says, "I will obtain for you the teaching of this surah," it is valid; because this is a benefit in his liability that is not specific to him, so it is permissible to hire someone (35) who knows it, just like sewing if he hires someone to obtain it for her. And if he says, "It is upon me to teach you," then the Qadi mentioned in "al-Jami'" that it is not valid; because it became specific to his own action, and he is unable to perform it, so it resembles the case where he hires someone who does not know how to sew to sew for him. And he mentioned in "al-Mujarrad" that it permits validity; because this is in his liability, so it resembles the case where he gives her wealth as a dowry that is in his liability but which he is unable to provide at the moment.

Section: If she comes to him with someone other than him and says: "Teach him the surah which you intend to teach me" (36), he is not obligated to do so; because what is due from him is the act upon a specific object, so he is not obligated to perform it upon another, just as if she had hired him to sew a garment (37), then brought him another and said: "Sew this." Furthermore, learners differ greatly in learning (38). Moreover, he has a purpose in teaching her, so he is not forced to teach another. And if he comes to her with someone else to teach her, she is not obligated to accept that; because teachers differ in their teaching, and because she...
