Three people came to the Messenger of Allah ﷺ and one of them said: I had one hundred Ooqiyyahs and I spent one Ooqiyyah (in charity). The next one said: I had one hundred dinars and i spent ten dinars (in charity). The next one said: I had ten dinars and I spent one dinar (in charity). The Prophet ﷺ said: “You are equal in reward, for each of you gave one tenth of his wealth in charity.”
جَاءَ ثَلاثَةُ نَفَرٍ إِلَى رَسُولِ اللهِ ﷺ فَقَالَ أَحَدُهُمْكَانَتْ لِي مِائَةُ أُوقِيَّةٍ فَأَنْفَقْتُ مِنْهَا عَشْرَةَ أَوَاقٍ وَقَالَ الْآخَرُ كَانَتْ لِي مِائَةُ دِينَارٍ فَتَصَدَّقْتُ مِنْهَا بِعَشَرَةِ دَنَانِيرَ وَقَالَ الْآخَرُ كَانَتْ لِي عَشَرَةُ دَنَانِيرَ فَتَصَدَّقْتُ مِنْهَا بِدِينَارٍ فَقَالَ النَّبِيُّ ﷺ أَنْتُمْ فِي الْأَجْرِ سَوَاءٌ كُلُّ إِنْسَانٍ مِنْكُمْ تَصَدَّقَ بِعُشْرِ مَالِهِ
