Mishkat al-Masabih, 1801

Anas reported God’s messenger as saying, “He who collects more <i>sadaqa</i> than is due is like him who refuses to pay it.” * Abu Dawud and Tirmidhi transmitted it. * Meaning that the sin committed by both is similar in its seriousness.

وَعَنْ أَنَسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الْمُعْتَدِي فِي الصَّدَقَةِ كَمَانِعِهَا» . رَوَاهُ أَبُو دَاوُد وَالتِّرْمِذِيّ
