May A Person Who Cannot Pronounce Some Letters Correctly Lead A Prayer?

May a person who cannot pronounce some letters correctly lead a prayer?

According to the preferred opinion, a person who cannot pronounce some letters due to his mouth structure may be the imam of the congregation if there is not any person among the congregation who can pronounce them correctly. But the imamah of such people is not permissible if there is someone among the congregation who can pronounce the letters correctly (Ibn Abidin, Radd al-Muhtar, II, 327-329; al-Fatawa al-Hindiyyah, I, 95).
