Slavery

Q: I want to know the concept of kaneez/loundi in Islam. Is this rule still applicable like the previous age? Or that was for the present time? If this practice has been stopped then how? What does the Qur'an say about it?

Wudhu breaking with a drop of urine

Q:

  1. Someone told me that if only a drop of urine comes out you still have your wudu because a drop is less than a penny (coin), is this true?
  2. All impurity which is less than 3 to 5 centimetres in diameter is excused. I am sure two drops of urine on your clothes will not make a circle which is more than 3 centimetres, is that true?
