There are two pronunciations and both support wiping.
1. You recite the feet with kasra: bi ru uusikum wa arjulikum. Some recite it like this.
2. Recite the feet with Fatha: bi ruusikum wa arjulakum. This in essence is : wamsahuu arjulakum. Because 'Mash' here is “ fi’il and “ faail’ and the word that comes after it takes fatha.
There is no ambiguity here at all. Most Sunnis use Hadith to justify which believe Hadith cannot contradict Quran
