Tests are the basis of this life

Allah Almighty said :

Who created death and life to test you and see whose deeds are better. He is the Mighty, the Forgiving. 67:2

He also said,
“Every soul will taste death. And we will certainly subject you to temptations, testing both good and bad” (Quran, 21:35).

The Messenger of Allah (peace and blessings of Allah be upon him) said: “There are two things that the son of Adam hates. He hates death, but death is better for him than confusion. And he hates small possessions, but few possessions are easier to calculate (on the Day of Judgment).”
? “Sahih al-Jami'” 139.

The Messenger of Allah (peace and blessings of Allah be upon him) said: “There is nothing left of this world but trial and turmoil. So prepare yourself for the test with patience!”
?Abu ‘Amr al-Dani in al-Fitan 3. Imam al-Dhahabi called the isnad of the hadeeth good. See Mizan al-i’tidal 4/443.

Allah Almighty also said: “ Do people think that they will be left and not subjected to temptation just because they say: “We believed”? We have already tempted those before them. Allah will certainly reveal those who speak the truth, and will certainly reveal the liars ”(Quran, 29: 2-3).

The Almighty also said: “ Or did you think that you would enter Paradise without experiencing what befell your predecessors? They were plagued by poverty and disease. They experienced such shocks that the Messenger and those who believed with him said: “When will the help of Allah come?” Verily, the help of Allah is near ” (Quran, 2: 214).

Allah Almighty also said: “We will certainly test you with something of fear, hunger, loss of property, people and fruits. Give joy to those who are patient” (Quran, 2: 155).

Allah Almighty in the Qur’an said: “Evil appears on land and on the sea because of what human hands commit, so that they taste part of what they have done, and so that they return to the straight path” (Quran, 30: 41).

Allah Almighty says: “Beware of trouble, which will strike not only those of you who were unjust” (Quran, 8: 25).

Ibn ‘Abbas (may Allah be pleased with him) said: “Allah ordered the believers not to agree with the reprehensible that is happening among them, and the consequence of their connivance will be that Allah will punish both those who do evil and those who are not involved.”
? (al-Baghawi 3/346).

Allah Almighty said: “This is because Allah does not deprive the mercy that He has bestowed on people until they themselves change what is in their souls. Verily, Allah is Hearing, Knowing” (Quran 8:53).
