Sabr is one of the most misunderstood word. People unnecessarily procrastinate and called it sabr.
The essence of word sabr is when it is impossible to survive & you are determined to stand up.
The lexicographers have given the example of dessert plant cactus for defining the word sabr. This plant survives in spite of intense dessert heat and lack of water, this is sabr, to stand up and work to survive in spite of all adversity.
