Sabr, like many other things mentioned int he Qur'an is an order to us from Allah (swt). The reason this needs serious discussion is because we spend a lot of time over the apparent duties we are ordered such as hijab and daily prayers, charity which are all very important as well but without the inner condition of the soul we cannot fully understand the true virtue behind them. Patience, like hijab is a very big challenge and a command from Allah (swt) that every Muslim should aim to attain.
have faith, be firm, keep steady and stay constant.
Lets all learn the virtues of SABR!
