عَنْ أَبِي هُرَيْرَةَ وَابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمْ
قَالَا: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا تَنْذُرُوا فَإِنَّ النَّذْرَ لَا يُغْنِي مِنَ الْقَدَرِ شَيْئًا وَإِنَّمَا يُسْتَخْرَجُ بِهِ من الْبَخِيل»
Abu Hurayrah and Ibn Umar reported God’s Messenger as saying, “Do not make vows, for a vow has no effect against fate; it is only from the miserly that it is a means by which something is extracted.”
