All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
There is nothing wrong with buying or sewing or wearing these cloths, even if the name “Ahmed” is written on it, and you do not have to do anything about it, as it is not necessarily that what is meant by it is our Prophet .
Just having the same name as the name of one of the Prophets does not necessitate that that name be treated completely as the name of the Prophet .
However, it must be venerated and respected if we know that what is meant by it is the Prophet such as when the expression: is mentioned after the name, or when the name is described with the Message and Prophethood, or the like.
Allah knows best.
