934 – Al-Harith ibn Usamah records, in the narration of ʿUbadah ibn al-Samit (may Allah be pleased with him) traced back to the Prophet: “Playfulness is not permissible in three matters: divorce, marriage, and emancipation. Whoever pronounces them, they become binding.” Its chain of transmission is weak (1).

— Hadith grading:
The hadith is weak.
Al-Harith ibn Abi Usamah cited it in his Musnad: “Bishr ibn ʿUmar narrated to us; ʿAbd Allah ibn Lahiʿah narrated to us; ʿUbayd Allah ibn Abi Jaʿfar narrated to us, from ʿUbadah ibn al-Samit.”
I say: this isnad is weak for two reasons:

1. The link between ʿUbayd Allah ibn Abi Jaʿfar and ʿUbadah ibn al-Samit is broken, for no direct hearing from any Companion is established for ʿUbayd Allah.
2. ʿAbd Allah ibn Lahiʿah is weak; al-Hafiz said, “He was truthful but became confused after his books were burned.”
   Yet Ibn Hajar, in al-Talqhis al-Habir, mentioned several routes for this report; all of them are weak, though they lend support to one another—and Allah knows best. Similar wording is also reported mawqūf from ʿUmar and from ʿAli.

— Vocabulary:
– wajabna (وَجَبْن): they became obligatory, confirmed, and their rulings took effect.

— Points derived from the two hadiths:

1. Both narrations show that the rulings in question—namely the marriage contract, divorce, the husband’s revocation that restores the marriage bond, and manumission—take effect immediately.
