Ayesha reported,

The Prophet ﷺ said, "Gentleness never enters anything without adorning it, and it is never removed from anything without disfiguring it."The narration adds that Ayesha was riding a camel that proved difficult, and she kept jerking it back and forth. So the Messenger of Allah ﷺ said to her, "Be gentle." Then he mentioned the same words.
