The Benefits of Buying and Selling From Other Faiths

In many muslim lands there still is let's say a lawn or an opening or a front room and the door would not be locked. Friends and relatives can come in anytime to this front room but they know that they don't go behind the curtain. When something good happens to you you fall down in sejda and that sejda does not need wudu because it's not salah  and we should also revive this habit every time a good news happens.
