al-Harith bin Abu Usamah reported from the Hadith of 'Ubadah bin as-Samit [RA) - tracing it to the Prophet (ﷺ):
"It is not permissible to play in three things: divorce, marriage and emancipation. Therefore, whoever pronounce (either of) them, they certainly become binding." [Its chain of narrators is Da'if (weak)].
