Punishment of one who carries alcohol and delivers it to someone else

It is haraam to drink alcohol or to sell it, carry it or help with it in any way whatsoever, because Allah says (interpretation of the meaning): 

“O you who believe! Intoxicants (all kinds of alcoholic drinks), and gambling, and Al‑Ansaab (stone altars for sacrifices to idols etc), and Al‑Azlaam (arrows for seeking luck or decision) are an abomination of Shaytaan’s (Satan’s) handiwork. So avoid (strictly all) that (abomination) in order that you may be successful” [Al-Maa’idah 5:90]

Abu Dawood (3674) and Ibn Maajah (3380) narrated that Ibn ‘Umar said: The Messenger of Allah (peace and blessings of Allah be upon him) said: “Allah has cursed alcohol, the one who drinks it, the one who pours it, the one who sells it, the one who buys it, the one who squeezes (the grapes etc), the one for whom it is squeezed, the one who carries it and the one to whom it is carried.” Classed as saheeh by al-Albaani in Saheeh Abi Dawood. 

Al-Tirmidhi (1295) narrated that Anas ibn Maalik said: The Messenger of Allah (peace and blessings of Allah be upon him) cursed ten with regard to alcohol: the one who squeezes (the grapes etc), the one for whom it is squeezed, the one who drinks it, the one who carries it, the one to whom it is carried, the one who pours it, the one who sells it and consumes its price, the one who buys it and the one for whom it is bought.” 

You did well not to accept this evil gift. This is what the Messenger of Allah (peace and blessings of Allah be upon him) did, as is narrated in Saheeh Muslim (1579): A man gave the Messenger of Allah (S) a small skin full of wine, and the Messenger of Allah (peace and blessings of Allah be upon him) said to him: “Do you know that Allah, may He be exalted, has forbidden it?” He said, No, then he whispered to another man. The Messenger of Allah (peace and blessings of Allah be upon him) said: “What are you whispering about?” He said: I told him to sell it. He said: “The One Who has forbidden drinking it has also forbidden selling it.” 

But you made a mistake when you carried it and accepted it for someone else. What you should have done is refuse to do that, and explain to the giver that alcohol is haraam and it is haraam to help with it, and you should not fear the blame of any blamers for the sake of Allah. 

What you must do now is repent to Allah and resolve not to do this again. 

You have to advise your boss and those who are with you not to drink alcohol, and to beware of it bad consequences, for it is the mother of all evils. 

It was narrated from Jaabir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: “Allah has made a covenant to those who drink alcohol, that He will make them drink teenat al-khabaal.” They said, “O Messenger of Allah, what is teenat al-khabaal?” He said, “The sweat of the people of Hell,” or, “The juice of the people of Hell.” Narrated by Muslim, (3732). 

May Allah help us all to do that which He loves and which pleases Him. 

And Allah knows best.
