Narrated Iyad bin Himar (RA):

Allah's Messenger (ﷺ) said: "He who finds something should call two trusty people as witnesses, keep in mind what it is contained in, and what it is tied with, and not conceal it or cover it up. Then, if its owner comes, he has the most right to it. Otherwise, it is Allah's property which He gives to whomever He wills." [Reported by Ahmad and al-Arba'a excluding Tirmidhi. Ibn Khuzaimah, Ibn al-Jarud and Ibn Hibban graded it Sahih (authentic)].

وَعَنْ عِيَاضِ بْنِ حِمَارٍ ‏- رضى الله عنه ‏- قَالَ : قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ مَنْ وَجَدَ لُقَطَةً فَلْيُشْهِدْ ذَوَيْ عَدْلٍ , وَلْيَحْفَظْ عِفَاصَهَا وَوِكَاءَهَا , ثُمَّ لَا يَكْتُمْ , وَلَا يُغَيِّبْ , فَإِنْ جَاءَ رَبُّهَا فَهُوَ أَحَقُّ بِهَا , وَإِلَّا فَهُوَ مَالُ اَللَّهِ يُؤْتِيهِ مَنْ يَشَاءُ } رَوَاهُ أَحْمَدُ, وَالْأَرْبَعَةُ إِلَّا اَلتِّرْمِذِيَّ , وَصَحَّحَهُ اِبْنُ خُزَيْمَةَ , وَابْنُ اَلْجَارُودِ , وَابْنُ حِبَّان َ [1]‏ .‏
