تَوْبًا تَوْبًا لِرَبِّنَا أَوْبًا لَا يُغَادِرُ عَلَيْنَا حَوْبًا
Tawban tawban li-Rabbina awban la yughadiru 'alayna hawba
Repentance, repentance to our Lord — a return that leaves no sin upon us.
Said upon returning home from a journey. The word "awb" means both physical return and spiritual return (tawbah). So when you arrive home, you are simultaneously returning to your house and returning to Allah in repentance. The du'a asks that this return be so complete that no sin remains — a clean slate to start life at home again.
