Does stuttering prevent one from disseminating the knowledge he has acquired?

Stuttering requires patience and training to speak slowly and confidently, seeking Allah's help. It can be psychological or organic and is treated by consulting specialists. The person afflicted with it is rewarded twice for seeking knowledge despite the difficulty. They can benefit others through writing, or by training in public speaking and confronting the challenge, as some scholars and academics have done. A stutterer can benefit students of knowledge in academic lessons even if they do not overcome their stuttering.
