عَنْ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «مَنِ احْتَكَرَ عَلَى الْمُسْلِمِينَ طَعَامَهُمْ ضَرَبَهُ اللَّهُ بِالْجُذَامِ وَالْإِفْلَاسِ» . رَوَاهُ ابْنُ مَاجَهْ وَالْبَيْهَقِيُّ فِي شُعَبِ الْإِيمَانِ. وَرَزِينٌ فِي كِتَابِهِ
Translation

Ibn ‘Umar reported God’s Messenger as saying, “If anyone with-holds grain for forty days thereby desiring a high price, he has renounced God and God has renounced him.” Razin transmitted it.
