Tafsir of Al-Maa'oun 107:3

And urges not the feeding of Al-Miskin. This is as Allah says,

كﻼ بل ﻻ تكرمون اليتيم

وﻻ تحاضون على طعام المسكين

Nay! But you treat not the orphans with kindness and generosity! And urge not one another on the feeding of Al-Miskin! (89:17-18) meaning, the poor man who has nothing to sustain him and suffice his needs. Then Allah says,

فويل للمصلين
