Answer
Wa `alaykum As-Salamu waRahmatullahi wa Barakatuh.
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
Picking a drunk person is not prohibited. If you come to know that this person carries wine or the like intoxicants, then you have to refrain from picking him.
Answering your question, Dr. Muhammad Salama, PhD, Islamic Studies in English, Assistant Professor at the Faculty of Islamic Sciences al-Madinah International University (Mediu), states:
It is basically permissible to work as a taxi driver. But as in any other job or profession, a Muslim has to abide by the teachings of his religion. Picking a drunk person is not prohibited. If this person carries a bag and you do not know what it contains, then you do not have to inquire. But if you come to know that this person carries wine or the like intoxicants, then you have to refrain from picking him.
Allah Almighty knows best.
