Three people came to the Prophet ﷺ and one of them said: O Messenger of Allah ﷺ, I had one hundred dinars and i gave ten of them in charity. The next one said: O Messenger of Allah ﷺ, I had ten dinars and I gave one of them in charity. The next one said: I had one dinar and I gave one-tenth of it in charity. The Messenger of Allah ﷺ said: “You are all the same in reward, for each of you gave one tenth of his wealth.”
جَاءَ ثَلاثَةُ نَفَرٍ إِلَى النَّبِيِّ ﷺ فَقَالَ أَحَدُهُمْ يَا رَسُولَ اللهِ كَانَتْ لِي مِائَةُ دِينَارٍ فَتَصَدَّقْتُ مِنْهَا بِعَشَرَةِ دَنَانِيرَ وَقَالَ الْآخَرُ يَا رَسُولَ اللهِ كَانَ لِي عَشَرَةُ دَنَانِيرَ فَتَصَدَّقْتُ مِنْهَا بِدِينَارٍ وَقَالَ الْآخَرُ يَا رَسُولَ اللهِ كَانَ لِي دِينَارٌ فَتَصَدَّقْتُ بِعُشْرِهِ قَالَ فَقَالَ رَسُولُ اللهِ ﷺ كُلُّكُمْ فِي الْأَجْرِ سَوَاءٌ كُلُّكُمْ تَصَدَّقَ بِعُشْرِ مَالِهِ
