Muwatta Imam Malik Book of Judgements, Hadith 27

Malik related to me from Ibn Shihab from Salim ibn Abdullah from his father that Umar ibn al-Khattab said, "Whoever revives dead land, it belongs to him."
Malik said, "That is what is done in our community."

وَحَدَّثَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، عَنْ أَبِيهِ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، قَالَ مَنْ أَحْيَا أَرْضًا مَيِّتَةً فَهِيَ لَهُ . قَالَ مَالِكٌ وَعَلَى ذَلِكَ الأَمْرُ عِنْدَنَا .
