Keeping the Qur'an behind one's back

Q: I have noticed in some parts of the world e.g. Pakistan, they lay great importance on not having the Quran behind ones back, to the extent that even if you are at the back of a small musjid and are reading Quran and someone in the first saff is directly in front of you, they would tell you to move and get very angry about it. On the other hand in many other countries sitting directly behind someone's back and reading Quran is not considered wrong. What is mufti sahebs view on this matter of the Quran behind the back?

Saving up to buy a house

Q: Me and my husband are saving money to buy a house. We live in a rented house at the moment in Australia. Sometimes I am confused whether we should save money to buy house, vehicle, etc or donate the money saved to the needy people and live our life in the rented property. Can money be saved to buy a house or we need to give it to the needy, I am confused. Jazakallah for the reply. Thanks.
