Is it permissible to address someone as "Abu Muhammad" with the first letter Mim pronounced with a ضمة (damma)?

There is no harm in using "Muhammad" as a kunya (agnomen) or a name, and in addressing someone by this kunya or name. Muslims use this name and kunya. The correct and eloquent linguistic pronunciation is with a damma on the first mim. We have previously clarified the permissibility of being named or using this as a kunya.
