Quran 9:6 At-Tawbah, ayah 6 of 129

وَإِنْ أَحَدٌ مِّنَ ٱلْمُشْرِكِينَ ٱسْتَجَارَكَ فَأَجِرْهُ حَتَّىٰ يَسْمَعَ كَلَـٰمَ ٱللَّهِ ثُمَّ أَبْلِغْهُ مَأْمَنَهُۥ ۚ ذَٰلِكَ بِأَنَّهُمْ قَوْمٌ لَّا يَعْلَمُونَ ۝٦

9:6 And if anyone of the idolaters seeketh thy protection (O Muhammad), then protect him so that he may hear the Word of Allah, and afterward convey him to his place of safety. That is because they are a folk who know not.
