The following hadith narrated by Anas ibn Malik (may Allah be pleased with him) proves his thoughtful character:
The Prophet said, “(It happens that) I start the prayer intending to prolong it, but on hearing the cries of a child, I shorten the prayer because I know that the cries of the child will incite its mother’s passions.” (Al-Bukhari)

In a another hadith,
Narrated Umm Khalid: I (the daughter of Khalid ibn Said) went to Allah’s Messenger with my father and I was wearing a yellow shirt. Allah’s Messenger said, “Sanah, Sanah!” (`Abdullah, the narrator, said that sanah meant “good” in the Ethiopian language). I then started playing with the seal of prophethood (between the Prophet’s shoulders) and my father rebuked me harshly for that. Allah’s Messenger said, “Leave her.” The Prophet, then, invoked Allah to grant her a long life thrice. (Al-Bukhari)
