Examples from the hadith of the Messenger that contradict the athar of Ibn Mas'ud (may Allah be pleased with him): (For you are not able to change his character until you change his nature).

The Shaykh : Take a clear example of that: his saying (peace and blessings be upon him): If a person is created with a temper, defiant and harsh, is there any benefit in treating it?

Man is created with deficiency so that he strives and struggles in the path of Allah (Mighty and Majestic). So, at the time we find a person to be generous, noble, and bountiful, we may find him to be angry, and vice versa. Thus, this noble person must treat his anger, and that stingy, patient person must treat his stinginess and miserliness, and so on.
