Riyad as-Salihin

'Abdullah bin 'Amr bin Al-'as (May Allah be pleased with them) reported: Messenger of Allah (ﷺ) said, "Neglecting one's own dependents is a reason enough for a man to commit a sin".

[Abu Dawud]

The narration in Muslim is: Messenger of Allah (ﷺ) said, "It is enough sin for a person to hold back the due of one whose provision is in his hand".
