‘A’isha reported the Prophet as saying, “He who develops land which has no owner has the best right to it.” ‘Urwa said that ‘Umar gave decision accordingly during his caliphate. Bukhari transmitted it.
عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنْ عَمَرَ أَرْضًا لَيْسَتْ لِأَحَدٍ فَهُوَ أَحَقُّ» . قَالَ عُرْوَةُ: قَضَى بِهِ عُمَرُ فِي خِلَافَتِهِ. رَوَاهُ الْبُخَارِيُّ
