Wa-alaykum as-salamu wa-rahmatullah wa-barakatuh

In the Name of Allah, the All-Merciful, the Mercy-Giving

All praise is due to Allah. Peace and blessings be upon His Messenger Muhammad.

As long as the drink is lawful, there is nothing wrong to take a sip from a friend. The problem, however, could be with unnecessary intermingling with female colleagues which opens the door for sinful acts. Islamic teachings have laid restrictions on the interaction between marriageable men and women to block all ways to evil practices.

Islam takes prohibitive measures and does not wait for evil to take place. Unnecessary mingling between marriageable men and women is not permissible and any contact has to be within the Islamic guidelines in this regard.

All evil practices between men and women are results of neglecting such teachings. Many non-Muslims have converted to Islam when they realized these facts and compared them with the loose life style they live in with all its negative impact on individuals, families and the whole society.

Almighty Allah knows best.
