the words and work of imam ibn al qayyim rahimahu allah
sahaba and patience
Deviations from the Straight Path did not appear in the Ummah until the people left the Revelation of Allaah and the methodology, clearly expounded by our pious predecessors, replacing it for man-made ideologies. This sometimes consisted of Greek philosophy as well as the ignorant deviations of man’s intellect. This changed the religion of Allaah, to such an extent that the Ummah splintered into groups, each of these developing its own methodology, way, leaders and followers.
