Wa`alaikum salaam warahmatullaahi wabarakaatuh.
What you're looking for are lectures on Akhlaaq/Aadaab. These were the ones I found. Inshaa'Allaah they're of benefit to all of us.
How to speak Guidelines/Guidance from the Qur'aan. Brother Nu`maan Ali khaan. The talk starts at 1:40
Drawing close to Allaah through Akhlaaq and Aadaab. Muhammad Al-Shareef (Almaghrib istructor) [It's just part 1/5, inshaa'Allaah you can find the rest on your own]
These two are by brother Kamal Al-Makki (another Al-Maghrib instructor)
Good Manners.
Akhlaaq.
And this one, I believe a brother here has already shared it. Br. Majed.
Islaam is all about good manners.
