Mishkat al-Masabih 10 The Rites of Pilgrimage كتاب المناسك 212

عَن يَعْلَى بْنِ أُمَيَّةَ قَالَ: إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «احْتِكَارُ الطَّعَامِ فِي الْحَرَمِ إِلْحَادٌ فِيهِ» . رَوَاهُ أَبُو دَاوُدَ

Ya’la b. Umayya reported God’s messenger as saying, “Storing up food to sell it at a high price in the sacred territory is a profanation of its sanctity.” Abu Dawud transmitted it.
