We always have plans pertaining to time,
At an age of this will do this and at age of that we should lead such and such life..
If the time isnt working as per our plan we get frustrated, complain and become ungrateful..
But have you ever thought of yousuf (AS) spending his youth in jail for no reason..
Zakriya (AS) having child in his old age..
Prophet Muhammad (SAW) hajj in his last days..
Allah does not work as per our timings his timings are best of timings never too late or never too early..
