Dua for the return of lost objects

اَللَّهُمَّ رَادَّ الضَّالَّةِ وَهَادِيَ الضَّلَالَةِ أَنْتَ تَهْدِيْ مِنَ الضَّلَالَةِ، اُرْدُدْ عَلَيَّ ضَالَّتِيْ بِقُدْرَتِكَ وَسُلْطَانِكَ فَإِنَّهَا مِنْ عَطَائِكَ وَفَضْلِكَ.

Transliteration

Allaahumma raaddad daallati wa haadiyad dalaalati anta tahdi minad dalaalah, urdud alayya daallati biqudratika wa sultaanika fainnahaa min ataaika wa fadlik.

Meaning

O Allah, the Returner of lost things, the Guide to the lost, You are the Guide to the lost. You, in your power and strength, give me back what I lost. Because, this object is given by you and I got it by your grace.
