TRIALS AND TESTS:-
Your question is not at all stupid but it is suited as to why Allah makes his loved servants suffer or put trial.
References to your question:-
And surely We shall try you with something of fear and hunger, and loss of wealth and lives and crops; but give glad tidings to the patient, Who says, when afflicted with calamity: “To Allah We belong, and to Him is our return”: They are those on whom (descend) Blessings from Allah, and Mercy, and they are the ones that receive guidance. (Al-Baqarah 2:155-157)
In another verse, Allah Almighty says:
He Who created Death and Life, that He may try which of you is best in deed: and He is the Exalted in Might, Oft-Forgiving. (Al-Mulk 67:2)
Whatever misfortune happens to you, is because of the things your hands have wrought, and for many (of them) He grants forgiveness. (Ash-Shura 42:30)
22:11 And there is, too, among befalls him, he is satisfied with Him; but if a trial assails him, he turns away utterly,  losing [thereby both] this world and the life to come: [and] this, indeed, is a loss beyond compare! 
HADITH (sayings and actions of the Prophet):-
