A Japanese teacher said to his pupils,
"To bow is to be like the willow, and to not return force is to be like the oak tree."
And in a hadith, the Prophet (bpuh) said:
"The believer is like the green plant; the wind blows it to the left and to the right."
The wise person is like water, for water does not crash into a rock, trying to pass through it. Instead, it comes to it from the left and from the right, from above and from below.
ln another hadith, the Prophet (Blessings and Peace be upon him) said:
"The believer is like a camel whose reins are on its nose. If it were made to kneel on a rock, it would do so."
