Dua When something is lost

اللَّهُمَّ رَادَّ الضَّالَّةِ وَهَادِي الضَّالَّةِ أَنْتَ تَهْدِي مِنَ الضَّلَالَةِ ارْدُدْ عَلَيَّ ضَالَّتِي بِقُدْرَتِكَ وَسُلْطَانِكَ فَإِنَّهَا مِنْ عَطَائِكَ وَفَضْلِكَ

"O Allah, the One who returns the lost, by Your power and awe return what I have lost, for surely I have received it as Your gift and favour (boon)".
