The Table Spread - 5:48
We have sent down to you this Book, which confirms the previous Books and replaces them, as a comprehensive truth, so judge between them by what Allah has sent down to you. Do not leave the truth that has come to you and follow their whim. We have appointed for each of you a law and a method, and if Allah had willed, He would have made you all one people. But He tests you with what He has given you. Compete in good deeds. To Allah is the return of all of you. He will inform you of the matters on which you differ.
How will we be tested?
The Cow/2:155
We will test you with fear, hunger, loss of money, lives, and crops. Give good news to those who are patient.
The Family Of Imran/3:186
You will be tested with your money and your lives. You will hear many insults from those who were given the Book before you and from those who associate partners. If you persevere and lead a virtuous life, you will have done a great deed.
