البيهقي:١٢٦٦٤ – وَبِهَذَا الْإِسْنَادِ عَنْ صَفْوَانَ بْنِ سُلَيْمٍ يَرْفَعُهُ قَالَ

قَالَ رَسُولُ اللهِ ﷺ السَّاعِي عَلَى الْأَرْمَلَةِ وَالْمِسْكِينِ كَالْمُجَاهِدِ فِي سَبِيلِ اللهِ وَكَالَّذِي يَصُومُ النَّهَارَ وَيَقُومُ اللَّيْلَ  

رَوَاهُ الْبُخَارِيُّ فِي الصَّحِيحِ هَكَذَا مُرْسَلًا عَنِ ابْنِ أَبِي أُوَيْسٍ عَنْ مَالِكٍ
