Sad 38:44

وَخُذْ بِيَدِكَ ضِغْثًا فَٱضْرِب بِّهِۦ وَلَا تَحْنَثْ ۗ إِنَّا وَجَدْنَـٰهُ صَابِرًا ۚ نِّعْمَ ٱلْعَبْدُ ۖ إِنَّهُۥٓ أَوَّابٌ

Wakhudh biyadika ḍigh'than fa-iḍ'rib bihi walā taḥnath innā wajadnāhu ṣābiran niʿ'ma l-ʿabdu innahu awwābun

[We said], "And take in your hand a bunch [of grass] and strike with it and do not break your oath."¹ Indeed, We found him patient, an excellent servant. Indeed, he was one repeatedly turning back [to Allāh].
