Sayyiduna Jabir (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "There is no divorce before marriage, no freeing before ownership, no suckling (that establishes fosterage) after weaning, no continuous fasting (wisal), and no keeping completely silent for a whole day."
