Reciting (Alaynaa in place of (Ilaynaa)

Q: Salaah-46: Whilst reciting Surah Ghaashiya in the second Rakaah of Jumu'ah salaah, our Imaam recited:
INNA ALAYNAA IYAABAHUM THUMM INNA ALAYNA HISAABAHUM.

instead of reciting:
INNA ILAYNA IYAABAHUM THUMM INNA ALAYNA HISAA BAHUM.
(He recite Alaynaa in place of Ilaynaa). Is the salaah valid or is it necessary to repeat the salaah?

Answer: The salaah will be valid in this case and there is no need to repeat it. And Allaah knows best what is most correct.
