Sunan Ibn Majah, Volume 5, Book 37, Hadith 4100 (DarusSalam) ⓘ
It was narrated from Abu Dharr Al-Ghifari that the Messenger of Allah said: “Indifference towards this world does not mean forbidding what is permitted, or squandering wealth, rather indifference towards this world means not thinking that what you have in your hand is more reliable than what is in Allah’s Hand, and it means feeling that the reward for a calamity that befalls you is greater than that which the calamity makes you miss out on.’”
حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا عَمْرُو بْنُ وَاقِدٍ الْقُرَشِيُّ، حَدَّثَنَا يُونُسُ بْنُ مَيْسَرَةَ بْنِ حَلْبَسٍ، عَنْ أَبِي إِدْرِيسَ الْخَوْلاَنِيِّ، عَنْ أَبِي ذَرٍّ الْغِفَارِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " لَيْسَ الزَّهَادَةُ فِي الدُّنْيَا بِتَحْرِيمِ الْحَلاَلِ وَلاَ فِي إِضَاعَةِ الْمَالِ وَلَكِنِ الزَّهَادَةُ فِي الدُّنْيَا أَنْ لاَ تَكُونَ بِمَا فِي يَدَيْكَ أَوْثَقَ مِنْكَ بِمَا فِي يَدِ اللَّهِ وَأَنْ تَكُونَ فِي ثَوَابِ الْمُصِيبَةِ إِذَا أُصِبْتَ بِهَا أَرْغَبَ مِنْكَ فِيهَا لَوْ أَنَّهَا أُبْقِيَتْ لَكَ " . قَالَ هِشَامٌ كَانَ أَبُو إِدْرِيسَ الْخَوْلاَنِيُّ يَقُولُ مِثْلُ هَذَا الْحَدِيثِ فِي الأَحَادِيثِ كَمِثْلِ الإِبْرِيزِ فِي الذَّهَبِ .
