Lillah and charity

Q: Is it more preferable for me to give sadaqah (old items) to my domestic worker who is a non-Muslim or to a reputable Islamic organization which donates to Muslims?

Q: I wanted to enquire if Iman (faith) is a necessary condition for purification of wealth (giving in charity, to purify one's wealth, without expectation of reward)? 

If a person does not identify as Muslim anymore, and has apostatized, and does not believe in the religion (does not believe Islam is from God but instead that it is man-made), but still believes in the financial aspects of Islam (eg: giving in charity and purifying any ill-wealth), would his purification of wealth be considered valid (as he is not a Muslim)? 

Would he need to repeat this purification of wealth (whatever sums of money he gave in charity with the intention of purifying his wealth) if he does tawbah and returns to Islam?

Q: Spending on charity is tax deductible. Is the reward of charity decreased if I claim tax back on my charity?

Q: If I allocate a certain amount of money every month for general sadaqah (poor, car guards, domestic etc.) then can I use from these monies sometimes for my kids or family if I run short or I need change etc.? As I understand that spending on ones family is also sadaqah? If I use from these monies for my family do I have to replace it?

Q: Is it permissible to give sadaqah to one's parents?

Q: My mother suggested to slaughter a goat every year as sadaqah and we do so. Can we give the price of that goat to some needy people as sadaqah? Remember that she already mentioned goat.

Q: A few month back I collected donations for my daughter's eye treatment. People kept sending money. Only one quarter of the collected amount was spent and the remaining amount is in my bank account. Is this money haraam for me?

Q: Can sadaqah be given towards the feeding scheme of a madressa to revert kids who are deserving cases and come from impoverished surroundings?

Q: What is the ruling of shariah with regards to taking pictures/videos of works of charity/welfare? Like digging a borehole, building masjids, food hampers, Qurbani, etc? Lot of Muslim organizations take pictures/videos of the charitable works done.

Q: I would like to know if clothes or any other items can be given as sadaqatul jaariyah?
