Two. The sentence with nothing behind it
Allah gives His hardest battles to His strongest soldiers.
It is on cards, on posts, on the wall of the ward. It is not a verse of the Qur'an and it is not a hadith. It has no chain. It is a modern saying, and it does a specific job, which is to make a struggling woman feel that asking for help would forfeit the compliment.
It is worth retiring, gently, whenever you see it.
Two more in the same family. That Allah does not burden a soul beyond its capacity means you must be able to cope with this, so stop asking. That verse is about legal obligation, about what you are required to do, and it is the basis for the concessions in lesson three. It lightens the load. It has never been a statement about how much distress a person can absorb in silence.
And that a mother's dua is always answered, so if you are still struggling something must be wrong with your state. That is a claim about somebody's standing with Allah, made from their symptoms, by a person who cannot possibly know. It is not established and it does real harm.
