THE FIQH DEPARTMENT

In the Name of Allah, The Most Beneficent, The Most Merciful.
Although every Fiqh opinion is based on evidence, often times, the scholars differ in their views. This room for differences is a mercy from Allah, and as long as there is evidence to support an opinion, then we must respect scholars' views, even if we may not always agree.
The Prophet (SAW) said:
"Whoever performs Ijtihad and errs will receive one reward. Whoever performs Ijtihad and arrives at the correct answer gets double the reward"

Ruling Concerning Mixing with the Disbelievers in order to Call Them to Islam PDF Print E-mail
Fiqh: Islamic Jurisprudence - Dawah: Calling to Allah
Written by Abdullah Ibn Jibreen   

Question: Is it allowed to mix with the disbelievers, Christians, Hindus and others, and to eat and talk to them or even to be amicable with them as a means of calling them to Islam?


Response: It is allowed to mix with the disbelievers, sit with them and be polite with them as means of calling them to Allah, explaining to them the teachings of Islam, encouraging them to enter this religion and to make it clear to them the good result of accepting the religion and the evil result of punishment for those who turn away. For this purpose, being a companion to them and showing love for them is overlooked in order to reach that good final goal.
