Beautiful manners

Shaikh Muḥammadu-bnu Ṣāliḥ al-ʿUthaymīn 
رحمه الله
said: 

"From the signs of a person’s good manners is his dealings with others and that he is someone easy to be around. His friends and family don’t find it difficult to be in his company nor does he make things difficult upon them."
