اِنَّ الَّذِيْنَ اٰمَنُوْا وَالَّذِيْنَ هَادُوْا وَالصَّابِـُٔوْنَ وَالنَّصٰرٰى مَنْ اٰمَنَ بِاللّٰهِ وَالْيَوْمِ الْاٰخِرِ وَعَمِلَ صَالِحًا فَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُوْنَ ( المائدة: ٦٩ )
Innal lazeena aamanoo wallazeena haadoo was saabi'oona wan Nasaaraa man aamana billaahi wal yawmil Aakhiri wa 'amila saalihan falaa khawfun 'alaihim wa laa hum yahzanoon (al-Māʾidah 5:69)
Indeed, those who have believed [in Prophet Muhammad (^)] and those [before him (^)] who were Jews or Sabeans or Christians – those [among them] who believed in Allah and the Last Day and did righteousness – no fear will there be concerning them, nor will they grieve. (Al-Ma'idah  : 69)
1 Mufti Taqi Usmani
Surely, those who believe, and those who are Jews, and the Sabians, and the Christians - whoever believes in Allah and the Last Day, and acts righteously, shall have no fear, nor shall such people grieve.
