it is clear that our most beloved trait of Muhammad ﷺ is the care and compassion he had for others.
He would ask about the health of the simple lady who would clean the Masjid.
He would treat everyone so special that each person would think that Muhammad ﷺ loved them the most.
He would be the first to send Salam to the people, and the last to let go of a handshake.
He would greet children and pat their heads, at a time where people looked down upon them.
He would turn towards a person completely when speaking to them.
And we can go on all day... But one verse sums it up completely:
سورة الأنبياء - Al-Anbiya: Verse 107
وَمَا أَرْسَلْنَاكَ إِلَّا رَحْمَةً لِلْعَالَمِينَ
We sent thee not, but as a Mercy for all creatures.
