In verse [ 33] we have the statement وَجَاءَ بِقَلْبٍ مُّنِيبٍ (...and comes up with a heart oriented towards Him....Qaf 50:33 ⧉]. Abu Bakr Warraq (رح) says that the characteristics of a munib is that he always maintains respect for Allah and humbles himself to Him and gives up his sensual and base desires.
