Quran Al-Hashr 59:9

وَٱلَّذِينَ تَبَوَّءُو ٱلدَّارَ وَٱلۡإِيمَٰنَ مِن قَبۡلِهِمۡ يُحِبُّونَ مَنۡ هَاجَرَ إِلَيۡهِمۡ وَلَا يَجِدُونَ فِي صُدُورِهِمۡ حَاجَةٗ مِّمَّآ أُوتُواْ وَيُؤۡثِرُونَ عَلَىٰٓ أَنفُسِهِمۡ وَلَوۡ كَانَ بِهِمۡ خَصَاصَةٞۚ وَمَن يُوقَ شُحَّ نَفۡسِهِۦ فَأُوْلَٰٓئِكَ هُمُ ٱلۡمُفۡلِحُونَ

Translation

And [also for] those who were settled in the Home [i.e.,al-Madīnah] and [adopted] the faith before them. They love those who emigrated to them and find not any want in their breasts of what they [i.e., the emigrants] were given but give [them] preference over themselves, even though they are in privation. And whoever is protected from the stinginess of his soul - it is those who will be the successful.
