Mukhtasar Muslim

´Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that` the Messenger of Allah (peace and blessings be upon him) said: No woman should observe (optional) fast while her husband is present at home except with his permission, and she should not allow anyone (of her mahram relatives) to enter his house while he is present except with his permission (and when he is not present, then all the more she should not allow anyone to enter except according to his prior instructions and consent). And whatever she spends from his earnings without his permission, then in that (reward) her husband has half the reward (i.e., the man gets the reward for earning and the woman for giving).
