«لَا تِرْحَمْ وَلَا تْخَلِّي رَحْمِةْ رَبِّنَا تِنْزِلْ»

The saying targets a person who is unhelpful twice over. They offer no compassion or support themselves, and they also get in the way of any relief that might come from elsewhere, here pictured as the mercy of our Lord coming down upon us.

The complaint is that withholding is not where this person stops; they also shut off other sources of good. The fault singled out is obstruction added on top of refusal, a second wrong layered over the first rather than mere holding back.

Addressed to, or said about, someone who gives nothing of their own and also stands in the way of help or kindness that might reach others from another quarter. It faults both the refusal and the interference in a single breath.
