The Quran

إِنَّ الَّذينَ آمَنوا وَالَّذينَ هادوا وَالنَّصارىٰ وَالصّابِئينَ مَن آمَنَ بِاللَّهِ وَاليَومِ الآخِرِ وَعَمِلَ صالِحًا فَلَهُم أَجرُهُم عِندَ رَبِّهِم وَلا خَوفٌ عَلَيهِم وَلا هُم يَحزَنونَ

(Saheeh International)

Indeed, those who believed and those who were Jews or Christians or Sabeans [before Prophet Muḥammad (ṣ)] – those [among them] who believed in Allāh and the Last Day and did righteousness – will have their reward with their Lord, and no fear will there be concerning them, nor will they grieve.¹

After the coming of Prophet Muḥammad (ṣ) no religion other than Islām is acceptable to Allāh, as stated in 3:85.
