Аль-Ахзаб 33:24

The lives of the Prophet and his companions were of an exemplary, godly character and were meant to be followed by all the faithful till the Day of Judgement. They set an example to show what it means to seek God’s pleasure and merit success in the Hereafter; what is meant by remembering God; how to be steady and persevering in difficult times; how reliance is placed on the promises of God; what ever-increasing faith is and how it is achieved; and how to fulfill the vows taken before God. The Prophet and his companions set the final example in all these matters. Under the most difficult circumstances, they did not falter. They were the embodiment of Islamic thought and Islamic character in all matters. Before the arrival of the moment of trial, they were firm in their acceptance of Truth and even after the arrival of that moment they remained unwavering. Then, it was the life of the Prophet and his companions which set an example and showed that no decision was taken by God, unless one was put to the test. It is the way of God that He creates severe conditions so as to separate the truly faithful from the false claimants. In this Divine precept and practice, there was no exception earlier and neither will there be any exception in future.
