Assalonhaleikom, wa rahmattoellah, Wa barakkatoe Bismillahir rahamannirrahim, I would like to ask for some advice for someone that is stottering when talking to people. I never stotter in my prayers. But when I talk to people it’s very difficult for me. I would like to ask you for some advice cause it is very difficult for me in my life and to seek knowledge that way.

All praise be to Allah, and may His Blessings and Peace be on His Last Messenger,
Seek Allah’s help and make abundant du’a’ (supplication)
I prescribe for you the du’a’ of Musa (blessings and peace be upon him):
[وَاحْلُلْ عُقْدَةً مِّن لِّسَانِي * يَفْقَهُوا قَوْلِي]
“And remove the impediment from my speech, So they may understand what I say”
Be patient, for that is an affliction like many others, and this life is a place for trials. Allah rewards those who are patient without reckoning.
Don’t feel embarrassed, and be comfortable with who you are. Your worth in front of Allah and the believers is congruent with what you have in your heart and what you do. The forms and bodies are not what Allah considers in evaluating his servants.
Seek medical treatment (speech therapy) and try to practice a lot.
May Allah reward you and give you the cure you are looking for.
