1) Reveal the Patient from the Impatient:
And certainly, We shall test you with a bit of fear, hunger, loss of wealth, lives and fruits. But give glad tidings to the patient ones who, when afflicted with a calamity, say: “Truly! To Allah we belong and truly, to Him we shall return.” They are those upon whom are the blessings, descend from their Lord, and they re...ceive His Mercy, and it is they who are guided.” (Surah Al-Baqarah 2:155-157)
2) Remove our Sins and Reward the Righteous:
“And, when he was old enough to walk with him, he said: “O my son! I have seen in a dream that I am slaughtering you, so what do you think?” He said: “O my father! Do that which you are commanded, if Allah Wills, you will find me to be of the patient.” Then, when they had both submitted, and he had laid him prostrate on his forehead, and We called out to him: “O Ibrahim! You have fulfilled the dream!” Verily! Such do We reward the good-doers.” (Surah as-Saffat :102-7)
Sa’ad bin Abi Waqqas reported that he asked the Messenger of Allah (SAW): “Which of the people are tested most severely?” Rasulullah (SAW) replied: “The Prophets, then the righteous, then those who are most like them, then those who are most like them from the people. A man is tested according to his religious commitment. So, if his religious practice is sound, then his testing is increased, and if his religious practice is weak, then his testing is reduced. A servant continues to be tested until he walks the Earth without a single sin on him.” (Ahmad, Tirmidhi)
3) Purify the Ranks and Distinguish the Righteous from the Wicked:
“Allah will not leave the believers in the state in which you are now until He distinguishes the wicked from the good.” (Surah Al ‘Imrân 3:179)
4) Emphasize the Hardships of This World in Comparison to the Hereafter:
“Blessed is He in Whose Hand is the kingdom, and He is Able to do all things. The One Who has created death and life in order to test you and see which of you is best in deed, and He is the All-Mighty, the Oft-Forgiving.” (Surah al-Mulk 67:1-2)
5) Expose the Reality of the Human Being:
“Verily, We have made that which is on earth as an adornment for it so that We may test them as to which of them are best in deeds.” (Surah al-Kahf 18:7)
