Shaykh Shah Wasiullah (Allah have mercy on him) said,

The objective of imparting ijaza and khilafa by the Shuyukh is that the people may consider these individuals trustworthy and develop a good opinion about them in order to benefit from them in their reformation (islah). It is not meant by it that the the person who has recieved this ijaza and khilafa to consider himself fully accomplished (kamil) and become negligent of his own reformation and start being independent of the pious Elders (akabir).’
