Is it permissible to use the term "master"?

The Shaykh : The questioner asks about a hadith that appears to contradict our previous ruling on the permissibility of using the word "master" as the Messenger (peace be upon him) used it for Sa'd ibn Mu'adh. There is another hadith that seems to conflict with this, but that is not the case upon careful examination. That hadith states that a group came to the Messenger (peace and blessings be upon him) and said to him: "You are our master and the son of our master." He responded to them by saying (peace be upon him): . It is clear that he did not approve of their use of the term "master" for the one who is the master of all humanity (peace and blessings be upon him). Nevertheless, the apparent meaning of the hadith is that he did not approve of their saying to him: "You are our master." In another hadith, in a story similar to this, they said to him: "You are our master and the son of our master." He said to them: . The hadith before this is explained in light of this. When he said to them: , it is as if (peace be upon him) sensed that these people were sanctifying him with this term and elevating him above the status that Allah placed him in. This is not permissible by the Shari'ah, as explicitly stated in the hadith: . So it is as if (peace be upon him) heard from the first group this term veiled with something of sanctity, from which he feared it might lead them to shirk (associating partners with Allah), or at least to some degree of shirk. Therefore, he blocked the door for them and clarified to them that true lordship belongs only to Allah (Blessed and Exalted is He). So he said to them: .
But this does not mean that it is not permissible for a Muslim to say to the Messenger (peace be upon him) that he is our master. How could it be, when he informed us in more than one authentic hadith that he is the master of people on the Day of Resurrection, and that Adam and all those below him will be under his banner (peace be upon him) on the Day of Resurrection? Rather, he wants us, when we use this term for him, and he is worthy of it, not to embellish it or mix it with any excess in his regard, from which the Messenger (peace be upon him) warned us in many hadiths. Among them is the hadith agreed upon by the two Shaykhs: . This is what he (peace be upon him) feared when he heard such a term from some people. People are not all equal in this prohibition. So when the Messenger (peace be upon him) sensed something of this prohibition from some of them, he cut them off from this term and directed them to their Lord (Mighty and Majestic), who has absolute lordship over him. Therefore, he said to them: . As for the other group, he treated them differently; he drew their attention to what might be feared from this usage. Therefore, he said to them: .
The Messenger (peace be upon him) clarified for us the prohibition that might occur from praising him (peace be upon him), even with something in which he is involved, which is a complete attribute... or say: "O our master," but beware, lest this word lead you to say about him (peace be upon him) what is not permissible. And glory to Allah, the Prophet (peace be upon him), as Allah said: . What the Messenger feared for his ummah (the Muslim community) has happened to the ummah, except for very few among them, who are those who constantly strive to adhere to the Sunnah and abandon the emotions that carry their owner away and know no limits. These emotions here corrupt a person's faith and thought. Therefore, you will find some people...
