[Ishaq]

It is permissible for kuffaar to enter Madeenah for the purposes of trade, without staying there.They should be given enough time (to complete their business) then they should be told to leave. Ibn Qudaamah (may Allaah have mercy on him) said:

It is permissible for them to enter the Hijaaz for the purpose of trade, because the Christians used to trade with Madeenah at the time of ‘Umar (may Allaah be pleased with him). An old Christian man came to him in Madeenah and said: “I am an old Christian man and your agent has taken the tithe from me twice.” ‘Umar said: “I am an old monotheist (haneef) man,” and ‘Umar wrote to the agent and said: “Only take the tithe once in a year, and do not allow them to stay for more than three days.”

Heißt das, dass Christen und Juden Handel in Makka und Madina betreiben können, aber unter einem Zeitlimit?
