Qur'an 38:44

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

“[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].”
