9:6
وَإِنْ أَحَدٌ مِّنَ ٱلْمُشْرِكِينَ ٱسْتَجَارَكَ فَأَجِرْهُ حَتَّىٰ يَسْمَعَ كَلَـٰمَ ٱللَّهِ ثُمَّ أَبْلِغْهُ مَأْمَنَهُۥ ۚ ذَٰلِكَ بِأَنَّهُمْ قَوْمٌ لَّا يَعْلَمُونَ
9:6
And if anyone of the Mushrikin seeks your protection then grant him protection so that he may hear the Word of Allah (the Qur'an) and then escort him to where he can be secure, that is because they are men who know not. - Safi-ur-Rahman al-Mubarakpuri (English)
