We are taking a new lesson. He spoke about Jabir, and I think we have taken it before, but I do not know how you did not hear it from us.

The Shaykh : In the name of Allah, the Most Gracious, the Most Merciful.
We are taking a new lesson. He spoke about Jabir, and I think we have taken it before, but I do not know how you did not hear it from us.
The student: ...

The Shaykh :" And from Jabir (may Allah be pleased with him), who said: The Messenger of Allah (peace and blessings be upon him) said:

Any slave who marries without the permission of his masters or owners is (like) a fornicator.

أيما عبد تزوج بغير إذن مواليه أو أهله فهو عاهر

Bulugh al-Maram 8:26

".
Here, "ayma" is a conditional particle, and "ma" is an extra word for emphasis. "Tazawwaja" (married) is the verb of the condition, and the clause is the answer to the condition.
And his saying: The "mawali" are those who originally freed him. The term "mawla" can also be used for the owner. It can be used for the owner, and that is what is intended here: the owner. This is because once he is freed, he owns himself, but as long as he is a slave, the authority belongs to his master. Allah the Exalted said: .
And his saying: The "aw" here indicates doubt from the narrator, meaning whether the wording of the hadith is "without the permission of his masters" or "without the permission of his family." The meaning is the same. So, who are the "mawali" intended here? The owners.
And his saying: "Al-'ahir" is a fornicator. "Al-'ahir" is the fornicator because his marriage is not valid, since a slave does not have the right to marry himself. The evidence for this in the Qur'an is the saying of Allah the Exalted: .
"Ibadakum" is the plural of "abd" (slave), which is the male slave. So, his saying: indicates that the slave does not marry himself; rather, he is married off. He is like the "ayyam" (free women) who have lost their husbands or been divorced; they do not marry themselves. Who marries them? Their guardian. Therefore, a slave marrying without the permission of his masters is like a woman marrying without a guardian.
