We were helping one low-paid office boy in our office every month with some money. But suddenly we discovered occasionally he drinks alcohol. So we decided we have to stop helping as per Hadith/order of Allah. At present we found that he has to leave the company as their contract expired. Is it permissible to give him money as farewell as per Hadith/ Qur'an?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

Anyone who is addicted to wine and insists on drinking it, or consumes that which causes drunkenness, or what is forbidden in the Sharee’ah is, in fact, a dissolute person. Befriending him, honoring him or showing affection to him is not permissible, because such a person is among those who oppose Allah and His Sharee’ah. A true Muslim should not love such a person. Allah Says in this concern (what means): {You will not find a people who believe in Allah and the Last Day having affection for those who oppose Allah and His Messenger, even if they were their fathers or their sons or their brothers or their kindred.} [Quran 58:22]

Allah knows best.
