Hadith 509
It is narrated from Sayyiduna Ali (may Allah be pleased with him): I have remembered six things from the Prophet (peace and blessings be upon him): Divorce will only take place after marriage, similarly, freedom will only be granted after ownership, and a vow to commit a sin should not be fulfilled, and orphanhood ends after reaching maturity, and there is no fast of silence until the night, and continuous fasting without breaking the fast is not permissible.
