Among the necessities or elements of faith (Al-Eemaan) is to be contented with all that is decreed: both what is good and what is bad. And certainly, we shall test you with something of fear; hunger loss of wealth, lives and fruits, but give glad tidings to the patient ones.
(Qur'an 2: I55)
What is decreed for us is not always in harmony with our desires and fancies. But then, we are not in a position to give suggestions. On the contrary, our right station and position is that of a worshipper, who surrenders his will.
We are all tested according to the level of our faith. The Prophet (Blessings and Peace be upon him) said:
"The pangs of death I feel are equal to what two of your men feel."
"The most severely tested of people are the Prophets and then the righteous ones."
Therefore be patient [O' Muhammad] as did the Messengers of strong will...)
(Qur'an 46: 35)
lf Allah wants good for a person, He afflicts him.
(And surely; We shall try you till We test those who strive hard [for the Cause of Allah] and the patient ones, and We shall test your facts [i.e. the one who is a liar and the one who is truthful].)
(Qur'an 47: 31)
(And We indeed tested those who were before them. ) (Qur'an 29: 3 )
