Lillah and charity

Q: If we give sadaqah in the form of money, is it necessary to inform the people who we are giving the money to that it is sadaqah or without telling them the sadqah will be valid?

Q: I have put a box in my cupboard in which I put the sadaqa amount and when a considerable amount gets together, I give them in charity. I have told my friends about it and they also sometimes contribute in it. The method I adopt regarding charity is that I visit a near by area where mostly poor people live. Then I search for those who are apparently religious as well as needy. The standard of needy that I look at is that one who is apparently really suffering to make both ends meet though he has a fruit stall or an animal like donkey for picking loads for people and carrying them elsewhere. I know that there must be much more needy ones but with this methodology, is my sadqa discharged properly because I think that giving to charity organization may be better but doing so one does not get the real feeling of the poor which one gets by searching them. So I prefer this method.

Q: I have recently adopted a practice of distributing food among people after jumma prayers out side mosque. My question is that I am not sure whether the people who take the food are really poor people or not? So in this stance please advise whether my this practice is beneficial for me or not?

Q: At work they collect money for non-Muslims deceased and or their family member. Can we give money for this collection?

Q: I'm currently expecting my 5th baby who will be due Insha Allah next year Feb or march. I'm very scared this time around. I don't really know why but my trust is firm with Allah. My question is that is it permissible if my husband and I sacrifice a sheep in the name of Allah when the time comes for delivery of baby in the hope that Allah will except and grant easy labour and fast swift delivery of baby and distribute the meat amongst the less fortunate? Is all of this permissible in Islam or not? An urgent reply will be highly appreciated.

Q:

1. Many a times Muslims beg for money inside and outside the mosque. Should or should I not give them? 

2. I donate money to charitable organizations, but I doubt whether the money reaches the poor.

Q: Is it more rewarding to buy gifts for one's family or to spend that money in sadaqah? (for the person who can't afford to do both)?

Q: What is the difference between Sadqah and Lillah?

Q: From the information I had available to me, I thought a sum of money was haraam interest. I gave this money to the poor without the intention of reward. I was later informed by the bank that in fact no interest was accruing in my account. I therefore gave out halaal money without the intention of reward. Will Allah Ta'ala still reward me despite the intention made at that time?

Q: Last couple of months my wife is very sick and I would like to give out Sadaqa. My question is 1:-What intention I must make? 2:-Can I give this Sadaqa to poor Non Muslims?
