9:121
وَلَا يُنفِقُونَ نَفَقَةٗ صَغِيرَةٗ وَلَا كَبِيرَةٗ وَلَا يَقۡطَعُونَ وَادِيًا إِلَّا كُتِبَ لَهُمۡ لِيَجۡزِيَهُمُ ٱللَّهُ أَحۡسَنَ مَا كَانُواْ يَعۡمَلُونَ ١٢١
Wa Lā Yunfiqūna Nafaqatan Şaghīratan Wa Lā Kabīratan Wa Lā Yaqţa`ūna Wa Adīāan 'Illā Kutiba Lahum Liyajziyahumu Al-Lahu 'Aĥsana Mā Kānū Ya`malūna
Nor do they spend an expenditure, small or large, or cross a valley but that it is registered for them that Allah may reward them for the best of what they were doing.
