بسم الله الرحمن الرحيم
Love demands sacrifice and sacrifice demands spending that which you have attachment with. The greater the attachment you have with a certain object/commodity/asset, greater will be the sincerity in your sacrifice.
By no means shall you attain Al-Birr (piety, righteousness – here it means Allâh’s Reward, i.e. Paradise), unless you spend (in Allâh’s Cause) of that which you love; and whatever of good you spend, Allâh knows it well.
[Surat Ale Imraan, 3:92]
