The source gives مَنْ يَقُولُ and مِنْ وَالٍ. The following letters are respectively yāʾ and wāw, so both take idghām with ghunnah.
Instead of a detached n between the words, flow into the next consonant with nasal resonance. Preserve the correct y- or w-sound and avoid making the passage artificially long.
