Mishkat al-Masabih, 3003

Tawus, in <i>mursal</i> form, reported God's Messenger as saying, “If anyone cultivates barren land it belongs to him, but ancient property belongs to God and His Messenger and then comes to you from me.” Shafi‘i transmitted it.

وَعَنْ طَاوُسٍ مُرْسَلًا: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «من أحيى مَوَاتًا مِنَ الْأَرْضِ فَهُوَ لَهُ وَعَادِيُّ الْأَرْضِ لِلَّهِ وَرَسُولِهِ ثُمَّ هِيَ لَكُمْ مِنِّي» . رَوَاهُ الشَّافِعِي
