«وَأُودِعُ مَعَارِفِي عَوَارِفِي»
I entrust my acquaintances with my benefactions.
Maʿārifī are those I know; ʿawārifī are my favours or benefactions. The similar forms connect acquaintance with active kindness: social recognition is not meant to remain mere greeting.
Ūdiʿu means to deposit or entrust. It makes benefaction something valuable that is deliberately placed in the hands of one's acquaintances.
