Qur'an 9:6

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

“And if any one of the polytheists seeks your protection, then grant him protection so that he may hear the words of Allāh [i.e., the Qur’ān]. Then deliver him to his place of safety. That is because they are a people who do not know.”
