Arabian Wisdom, by John Wortabet, [1913], at sacred-texts.com

Rashness

Beware of rashness, for it has well been called the Mother of Regrets.

He who acts hastily either makes a blunder, or comes very near it.

p. 50

He who is deliberate is either right, or very nearly so.

A hasty act comes from the Evil One, and a deliberate act from God.

Haste is the resort of the weak.
