«وَنَتَحَاذَى فِي الْفِعَالِ حَذْوَ النِّعَالِ»
Let our actions correspond as closely as a pair of shoes.
Fiʿāl denotes actions; ḥadhw describes correspondence or following the same pattern. The pair of shoes gives a homely simile of parity.
The preceding line weighed speech; this one aligns conduct. Together they state that fairness should appear not only in words, but also in what the two parties do for one another.
