وَعَنْ رَافِعِ بْنِ خَدِيجٍ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ مَنْ زَرَعَ فِي أَرْضِ قَوْمٍ بِغَيْرِ إِذْنِهِمْ, فَلَيْسَ لَهُ مِنْ اَلزَّرْعِ شَيْءٌ, وَلَهُ نَفَقَتُهُ } رَوَاهُ أَحْمَدُ, وَالْأَرْبَعَةُ إِلَّا النَّسَائِيَّ, وَحَسَّنَهُ اَلتِّرْمِذِيُّ [1]‏ .‏
