Who says, "When I have learned, I will return"? Is it a need? When the need ends, does he return?

The questioner : He says, "When I have learned, I will return"? What is the need? When his need ends, does he return?

The Shaykh : No, because knowledge is known not to be learned in a day and a night.

The questioner : It may take two years.

The Shaykh : For example, he says his need may be fulfilled in a day and he returns. Because knowledge is not learned in a day and a night.
