The word, Wallahul Musta’aan, as mentioned in the Quran, was said by Yaqoob عليه السلام when his sons came up with a false story of what happened to Yousuf عليه السلام. Yaqoob tried his best to find the truth but his sons teamed up to defend their heinous act and lies. Tired of the situation, Yaqoob asked Allah for Sabrun Jameel (beautiful patience) followed by Wallahul Mustaa’an.
According to the commentators of the Quran, Wallahul Musta’an is used to call for Allah’s help when you find yourself in impossible situations, when people team up against you to defend their lies, when people accuse you of something false, when you have given your best and desperately waiting for desired results, when you feel you’re in a situation where there’s no way out. It’s literally saying to Allah that I have given my best and now I am taking a backseat, I want You to take charge of the driving seat and solve this matter with your Divine intervention.
And patience automatically becomes beautiful when, with all your heart, mind, and soul you leave the matter to Allah.
Don’t worry if the situation seems impossible, remember you’re asking the One who just have to say ‘Kun’ — be and it is.
You are asking the One who calls Himself, Al-Fattah — the opener; Who creates a way out when there seems to be no way. So take a backseat and let Allah do the rest.
Wallahul Musta’an – “Allah is the one sought for help”
