فَمَا لَا يَكُونُ مَقْرُونًا بِالْإِيمَانِ وَالْعَمَلِ الصَّالِحِ يَكُونُ اسْتِدْرَاجًا
An extraordinary occurrence without faith and righteous action can be istidrāj.
Istidrāj concerns an apparent favor associated with pride, falsehood or heedlessness. Spectacular activity is not enough to classify something as a karāmah.
Claims to sainthood must be assessed in relation to belief, obedience and purpose. Judgments concerning specific individuals still require reliable evidence.
