Narrated 'Abdullah bin 'Umar (RA):

Allah's Messenger (ﷺ) said: "It is enough for a person to be considered sinful, that he neglects those whom he is responsible to sustain." [Reported by an-Nasa'i].

وَعَنْ عَبْدِ اَللَّهِ بْنِ عَمْرٍو رَضِيَ اَللَّهُ عَنْهُمَا قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ كَفَى بِالْمَرْءِ إِثْمًا أَنْ يُضَيِّعَ مَنْ يَقُوتُ.‏ } رَوَاهُ النَّسَائِيُّ.‏ [1]‏ .‏
