Yes. In a hadith qudsi Allah says that He has made oppression unlawful for Himself and unlawful among people, so do not oppress one another. The Quran warns that Allah is not unaware of what the wrongdoers do (14:42).
اور (مومنو) مت خیال کرنا کہ یہ ظالم جو عمل کر رہے ہیں خدا ان سے بےخبر ہے۔ وہ ان کو اس دن تک مہلت دے رہا ہے جب کہ (دہشت کے سبب) آنکھیں کھلی کی کھلی رہ جائیں گی
الزام تو ان لوگوں پر ہے جو لوگوں پر ظلم کرتے ہیں اور ملک میں ناحق فساد پھیلاتے ہیں۔ یہی لوگ ہیں جن کو تکلیف دینے والا عذاب ہوگا
