How do we know that we do not have competitors in our heart for the love of Allah? It is not stone idols any more but it can be many other things. It can be our family members, money or careers. We will never come out and say directly we love our money more than Allah. However, it will be shown in our actions, for example we will choose what we love most over the other. When we are tested we are always going to choose the ones that we love the most. SubhanAllah.
