Silsilat al-Ahadith al-Sahihah

Narrated from Sayyiduna Jarir bin Abdullah (may Allah be pleased with him), the Prophet Muhammad (peace and blessings be upon him) said: "When a relative goes to another relative and asks for something extra that Allah Almighty has given him, but he is stingy (and does not give), then on the Day of Resurrection a snake will be brought out from Hell for such a person, which will have its tongue out and will be called «شجاع», and it will be made into a collar for that person."
