Excellence of Generosity and Spending in a Good cause with Reliance on Allah
وَعَنْ جَابِرٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: مَا سُئِلَ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ شَيْئًا قَطُّ فَقَالَ: لاَ. ((مُتَّفَقٌ عَلَيْهِ)).
Jabir (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) never said 'no' to anyone who asked him for anything. [Al-Bukhari and Muslim].
