Sad 38:44

Wakhuth biyadika dighthan fadribbihi wala tahnath inna wajadnahu sabiranniAAma alAAabdu innahu awwab

[We said], "And take in your hand a bunch [of grass] and strike with it and do not break your oath." Indeed, We found him patient, an excellent servant. Indeed, he was one repeatedly turning back [to Allāh].

And (We said to him,) “Take (a bundle of) thin twigs in your hand, and strike with it, and do not violate your oath. Surely, We found him very enduring. He was really an excellent servant. Surely, he was great in turning (to Us, in penitence and praise).
