كتاب الأحكام
Read the English translation first, with the original Arabic directly underneath.
Narrated 'Abdullah bin 'Umar:
I have heard 'Umar saying, "The Prophet (ﷺ) used to give me some money (grant) and I would say (to him), 'Give it to a more needy one than me.' Once he gave me some money and I said, 'Give it to a more needy one than me.' The Prophet (ﷺ) said (to me), 'Take it and keep it in your possession and then give it in charity. Take whatever comes to you of this money while you are not keen to have it and not asking for it; take it, but you should not seek to have what you are not given. ' "
خُذْهُ فَتَمَوَّلْهُ وَتَصَدَّقْ بِهِ، فَمَا جَاءَكَ مِنْ هَذَا الْمَالِ وَأَنْتَ غَيْرُ مُشْرِفٍ وَلاَ سَائِلٍ فَخُذْهُ، وَمَا لاَ فَلاَ تُتْبِعْهُ نَفْسَكَ
