Zakaat

Wife giving Sadaqah from the husbands wealth without his permission

Q: Please tell me can a woman give Sadqah and khairaat without the permission of her husband from his income? 

Hadith: Narrated Abu Huraira: The Prophet (Sallallahu Alayhi Wasallam) said, "If the wife gives of her husband's property (something in charity) without his permission, he will get half the reward." Book 69, Sahih al-Bukhari 5360

Sadaqah

Q: Should I give money to people selling stuff that I don't need to buy without buying anything from them? 

Giving Zakaat before its due time

Q: I told the brothers they can pay zakah earlier then the time it is due. Example Ramadaan is in a week so give it now to benefit the poor. The people said it makes no sense. They said, then why can I not fast a month earlier. Why can I not pray salaah a day before. Is it that we can give zakaah earlier because it is to benefit the poor? Can you please help me answer this brother.

Zakaat on graded Mandela coins

Q: I have a few graded Mandela R5 coins (year 2000 and 2008) that I have acquired. They are legal tender, but because of their demand and rarity, I bought them for a few thousand rands. I purchased them with an investment intention. How do I pay zakaat on them?  The coins have no gold or silver in them.
