There is never a day wherein servants (of God) get up at morn, but are not visited by two angels. One of them says: 0 Allah, give him more who spends (for the sake of Allah), and the other says: 0 Allah, bring destruction to one who withholds.  

قَالَ رَسُولُ اللَّهِ ﷺ مَا مِنْ يَوْمٍ يُصْبِحُ الْعِبَادُ فِيهِ إِلاَّ مَلَكَانِ يَنْزِلاَنِ فَيَقُولُ أَحَدُهُمَا اللَّهُمَّ أَعْطِ مُنْفِقًا خَلَفًا وَيَقُولُ الآخَرُ اللَّهُمَّ أَعْطِ مُمْسِكًا تَلَفًا
