It is narrated from the Messenger of Allah (peace and blessings be upon him) that he (peace and blessings be upon him) said: "Gifts to officials (hadaya al-'ummal) (gifts given to officials and state agents) are all of them unlawful."
Imam Ahmad (may Allah have mercy on him) recorded this hadith in his Musnad. This prophetic saying shows that a gift received because of a public office or responsibility falls, in Islamic law, under the ruling of embezzlement and breach of trust.
