Explanation of the author's statement: Ibn Mas'ud (may Allah be pleased with him) said

The Shaykh : (peace and blessings be upon him), which is the seal. A testament means a covenant, and a covenant is not a testament unless it concerns a matter of great importance. His saying "Muhammad (peace and blessings be upon him)" means the Prophet. This expression by Ibn Mas'ud indicates the permissibility of such expressions, like saying "Muhammad the Messenger of Allah" or "the testament of Muhammad" and the like. This does not contradict the words of the Exalted: because this is calling the Messenger, i.e., addressing him. So do not address him by saying "O Muhammad," but say "O Messenger of Allah." As for the statement, it is broader than the category of calling, so it is permissible to say that you follow Muhammad, or that you follow Muhammad (peace and blessings be upon him).
The student: ... follow Muhammad

The Shaykh : Yes, follow Muhammad, or "O Allah, send blessings upon Muhammad," or the like.
And his saying: "which has his seal upon it". The word *khatam* (seal) means... *khatam* means... It was called among us the *mahr* (bridal gift), I do not know what the reason for this naming is. So the meaning is that these verses are like a will from the Messenger (peace and blessings be upon him). Otherwise, the Prophet (peace and blessings be upon him) did not leave a will for anything. The hadith of 'Abdullah passed by us when Abu Juhayfah asked him, "Did the Prophet (peace and blessings be upon him) leave a will for you?" He said, "He did not leave a will for us for anything except understanding that Allah the Exalted grants to one of the Qur'an, and what is in this sheet." So here, do not think that the Messenger (may Allah's prayer and peace be upon him) left a specific will for these verses. But the meaning is that these verses are in the position of a will, because Allah said to him: to the end of it. He says: "So let him read the saying of Allah the Exalted

Say, "Come,

قل تعالوا

to His saying

And that this is My path, straight

the verse". The speech about the verse has preceded.
