Is it correct to pronounce the letter "fa" in the word (كُفُواً) with sukun, making it (كفْواً)?

If a person recites "kufwan" with a sukoon on the fa and with ibdal according to the narration of Hafs, then he is mistaken. However, Isma'il ibn Ja'far, one of the narrators of Abu Ja'far (one of the ten reciters), narrated "kufwan" with a sukoon on the fa. An-Naysaburi mentioned in "Al-Mabsut fi Al-Qira'at Al-Ashr" that Hafs from Asim recited {kufuwan} with a dhammah on the fa, a fathah on the waw, and without a hamza. Similarly, Ibn Jammaz narrated it from Abu Ja'far, while Isma'il ibn Ja'far narrated it from him with a sukoon on the fa and without a hamza.
