Compare two word orders in the report about giving charity secretly:
حَتَّى لَا تَعْلَمَ شِمَالُهُ مَا تُنْفِقُ يَمِينُهُ
His left hand does not know what his right hand spends.
حَتَّى لَا تَعْلَمَ يَمِينُهُ مَا تُنْفِقُ شِمَالُهُ
His right hand does not know what his left hand spends.
In the second wording, shimāl and yamīn have exchanged places. This is the reversal illustrated here.
1. Shimāl: left hand. Yamīn: right hand.
