Assalamu alaikum wa rahmatullahi wa barakatuhu!
In the Name of Allah, Most Gracious, Most Merciful
When it came to manners, the Prophet Muhammad (saw) was superior to all other people. And why would he not be so, for it was Allah who guided him, trained him, and refined his character. As such, the Prophet (saw) had the best manners; he was the most truthful human being in speech; he was the most rightly-guided person; he feared Allah the most; he was the kindest of all people towards his relatives; he was the bravest person to have ever walked the earth; he was the most generous of people; he was the most just of all people; and he was, in every other way, the most superior of all people. All of this was a natural consequence of the Prophet (saw) being nurtured, cared for, trained, and taught by Allah.
Because of his wonderful qualities, the Prophet (saw) was near and dear to the hearts and souls of people. He was blessed and easy going, and yet he had about himself an aura of dignity and gravity that suited his lofty character. His face shone with the light of guidance; his mouth smiled with love; his heart was truly alive; and his mind was illuminated with elevated thoughts.
He had the uncanny ability of making all those around him happy, and of making all of his Companions feel at ease. While he loved favourable signs (signs that make one feel that something good will happen), he detested evil omens: the former, he (saw) knew, prompted one to be positive and to act well; the latter, on the other hand, made one pessimistic and deterred one from performing good deeds.
It was the Prophet's (saw) wont to pardon and forgive the mistakes of others. And he was generous, more generous, in fact, than gentle wind or much needed rain. He subdued people, not with a sword, but with generosity and good manners. With his message, he brought happiness to mankind. Whoever saw him, loved him; whoever knew him, stood in awe of him; and whoever met him, venerated him. His speech captivated people's hearts, and his noble manners at once tamed and subjugated people's souls.
Allah made his heart firm and steadfast, so that it never deviated from the truth. Allah guided his speech, so that he never spoke ignorantly. Allah safeguarded his Faith, so that he never went astray. And, Allah supported his mission, so that he was never forsaken or forced into despair. In every way imaginable, he was blessed and guided.
And verily, you (O Muhammad) are on an exalted standard of character.
(Surah Qalam - Verse 4)
And by the Mercy of Allah, you dealt with them gently ..
(Surah Aale-Imran - Verse 159)
The Prophet (saw) said: "The person among you who fears Allah the most and is most knowledgeable about Allah, is me".
In another hadith, he said: "The best among you is he who is the best towards his family. And among you all, I am the one person who stands out as being the best towards his family."
He (saw) is also related to have said: "Verily, I have been sent only to make complete (both in myself and others) the noblest of manners".
All the Glory be to Allah, Who chose the Prophet (saw), raised him, protected him, guided him, and looked after him.
