Making Sense of Hardship and the Reality of Evil in Our World

Salaam, everyone. Sometimes I find myself grappling with things that are truly difficult to comprehend. Seeing innocent people suffer, whether it's the young being mistreated, the vulnerable being exploited, or even harm within our own communities-like jealousy, backbiting, family disputes, financial struggles, and intentional hurt-can really shake my heart. I know the basics: that Allah (SWT) has granted us free will, that this life is a test, and that He doesn't intervene in every single action because accountability comes on the Day of Judgment. But honestly, it's still a struggle sometimes. Why must such intense pain exist, especially for those who seem blameless? How can things like sihr (witchcraft) causing separation or illness be allowed? I'm not asking from a place of rebellion, but from genuine confusion. I want to understand how we can hold firm to our belief in Allah's ultimate justice and mercy while witnessing the painful realities around us every day. How do you all find peace with this? Have any Quranic verses, hadith, or explanations from trusted scholars offered you clarity? I'm really trying to strengthen my iman and be honest about these struggles. Jazakum Allahu khairan for any insights you can share.
