الشرح المختصر

"Karaahat Tanzeeh" (undesirability qua blamelessness) or "karaahah" is a light prohibition regarding doing something, but one is not obliged to comply. In this respect, one gets reward for not doing it out of obedience to Allah and His Messenger, may Allah's peace and blessings be upon him. Meanwhile, one who does it, does not deserve a punishment. Hanafi school of Fiqh use it meaning that something is prohibited in a speculative way.
