ابن ماجة:٢٥٣٧ – حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ حَدَّثَنَا سَعِيدُ بْنُ سِنَانٍ عَنْ أَبِي الزَّاهِرِيَّةِ عَنْ أَبِي شَجَرَةَ كَثِيرِ بْنِ مُرَّةَ عَنِ ابِنْ عُمَرَ

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِقَامَةُ حَدٍّ مِنْ حُدُودِ اللَّهِ خَيْرٌ مِنْ مَطَرِ أَرْبَعِينَ لَيْلَةً فِي بِلاَدِ اللَّهِ ﷻ
