عَن سعيد بْنِ زَيْدٍ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ: «من أحيى أَرْضًا مَيْتَةً فَهِيَ لَهُ وَلَيْسَ لِعِرْقٍ ظَالِمٍ حق» . رَوَاهُ أَحْمد وَالتِّرْمِذِيّ وَأَبُو دَاوُد وَرَوَاهُ مَالِكٌ عَنْ عُرْوَةَ مُرْسَلًا. وَقَالَ التِّرْمِذِيُّ: هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ

Al-Hasan on Samura’s authority reported the Prophet as saying, “When any of you comes upon animals whose owner is among them he must ask his permission; if not he must call three times and if anyone answers him he must ask his permission; but if no one answers him he may draw some milk and drink, but not carry any away.” Abu Dawud transmitted it.
