Benefits regarding the types of implications: "correspondence, inclusion, and necessity."

The Shaykh : I promised you that you would review the benefits contained therein and write them down. If you wish, mention the verses first and then list the benefits without explaining those that require explanation. If you wish, mention each verse on its own and say, "It is derived from this verse such and such." There is no harm in that. Yes, let us see if we can obtain more benefits. Al-Shafi'i (may Allah have mercy on him) derived a thousand benefits from the words of the Prophet (peace and blessings be upon him) , which are two words and ten verses in meaning. This necessitates that we derive ten thousand from them. In any case, fear Allah as much as you are able, and the favor of Allah is given to whom He wills. For this reason, when a man said to 'Ali ibn Abi Talib, "Did the Prophet (peace and blessings be upon him) bequeath to you anything?" , and he mentioned what is in this document. The point is that people differ in their acquisition of knowledge, not only according to the amount of reading, but according to the amount of reading and according to understanding. Because you will find some scholars who review a verse and derive a great many benefits from a single verse, from the apparent implication, the implication of correspondence, and the implication of commitment. For the implications, as is known to you, are implication of inclusion, correspondence, and commitment. The implication of speech regarding its full meaning is called implication of correspondence. Its implication regarding a part of its meaning is called implication of inclusion. And its implication regarding a matter that necessitates such and such is called implication by commitment. For example, if I say "this is a house," this word implies the entire house, with its rooms, its stone, and its terraces, by implication of what? Correspondence. And its implication that it has a room, a chamber, and a terrace is implication of inclusion. And its implication that it has a builder who built it is implication by commitment, because it is necessary from its existence that it has a builder. So these three implications differ greatly among people, and according to this difference, the knowledge of a person expands. Therefore, the student should train himself in the frequent derivation of benefits from the texts, because from one text you may take a page of benefits and issues, while another person may not get even two lines from it. Therefore, the student of knowledge, just as he trains himself in frequent reading and reading books, should also train himself in deriving from the evidence. How many a single piece of evidence has indicated hundreds of issues according to the understanding of the person, so he is thereby spared the need for many texts and does not need to strain himself to acquire and read them. Yes, that is right.

The Shaykh : O Abu 'Amir, what has happened to the Nughayr? The Nughayr is a small bird that is played with, and it was with a boy who had this kunya (nickname) to play with. So when it died and this boy grieved, as is the custom of a boy, he held a bird and was happy with it. So when his bird died, he grieved over it, until some children play with it even while it is dead. So the Prophet (peace and blessings be upon him), when he entered one day and found the boy sad over the loss of this Nughayr, said to him ...
