From the Manners of Giving Advice

The shaikh, Dr. Muḥammad ibn Ghālib Al-ʿUmarī, may Allāh protect him, said:

Watch out you don’t give advice [to people, coming to them] from a high level. Show some compassion and be a little easy to deal with when [you’re] giving advice and give it in a nice way that brings about conviction and leads to acceptance; accepting the truth is heavy on the souls of many.

So your holding on to your rough, poor manners on the basis that the truth is with you is not going to bring hearts closer or make them inclined toward what’s right.

وَلَوۡ كُنت فَظًّا غَلِیظ ٱلۡقَلۡبِ لَٱنفَضُّوا۟ مِنۡ حَوۡلِك

Were you to be rough in the way you speak, harsh and hard-hearted, they would splinter away from you into all different directions. (Āl ʿImrān, 159)
