Hadith 8:132
‘Umar b. al-Khattab told of hearing God’s Messenger say, “If anyone keeps grain from the Muslims waiting for the price to rise, God will smite him with tubercular leprosy* and insolvency.” Ibn Majah, Baihaqi, in Shu'ab al-iman , and Razin in his book transmitted it. * Judham.
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
