He who hoards is a sinner. It was said to Saʿid (b. al-Musayyib): You also hoard. Saʿid said: Maʿmar who narrated this hadith also hoarded. (Using translation from Muslim 1605a)
قَالَ رَسُولُ اللهِ ﷺ مَنِ احْتَكَرَ فَهُوَ خَاطِئٌ فَقَالَ إِنْسَانٌ لِسَعِيدٍ فَإِنَّكَ تَحْتَكِرُ فَقَالَ سَعِيدٌ مَعْمَرٌ الَّذِي كَانَ يُحَدِّثُ هَذَا الْحَدِيثَ كَانَ يَحْتَكِرُ
