Best charity is to a close relative
أَفْضَلُ الصَّدَقَةِ عَلَى ذِي الرَّحِمِ الْكَاشِحِ
Afdalu-s-sadaqati ala dhi-r-rahimi-l-kashih.
"The best charity is to the relative who harbours animosity."
Narrated by Abu Ayyub. Musnad Ahmad 23074
A short reflection
Not the stranger you will never see again. The cousin who slighted you. The uncle who cut ties. That gift carries the highest reward, because it costs the most.
