Allah the Merciful has praised the Sahaba and mentioned them as being the truthful in the Quran;
مُّحَمَّدٌ رَّسُوۡلُ اللّٰهِؕ وَالَّذِيۡنَ مَعَهٗۤ اَشِدَّآءُ عَلَى الۡكُفَّارِ رُحَمَآءُ بَيۡنَهُمۡ تَرٰٮهُمۡ رُكَّعًا سُجَّدًا يَّبۡتَغُوۡنَ فَضۡلاً مِّنَ اللّٰهِ وَرِضۡوَانًاسِيۡمَاهُمۡ فِىۡ وُجُوۡهِهِمۡ مِّنۡ اَثَرِ السُّجُوۡدِؕ ذٰلِكَ مَثَلُهُمۡ فِىۡ التَّوۡرٰٮةِ وَمَثَلُهُمۡ فِىۡ الۡاِنۡجِيۡلِ كَزَرۡعٍ اَخۡرَجَ شَطَاهٗ فَاٰزَرَهٗ فَاسۡتَغۡلَظَ فَاسۡتَوٰى عَلٰى سُوۡقِهٖ يُعۡجِبُ الزُّرَّاعَ لِيَـغِيۡظَ بِهِمُ الۡكُفَّارَ ؕ وَعَدَ اللّٰهُ الَّذِيۡنَ اٰمَنُوۡا وَعَمِلُوۡا الصّٰلِحٰتِ مِنۡهُمۡ مَّغۡفِرَةً وَّاَجۡرًا عَظِيۡمًا
“Muhammad is the Messenger of God.
Those who follow him are harsh towards the disbelievers and compassionate towards each other.
You see them kneeling and prostrating, seeking God’s bounty and His good pleasure: on their faces they bear the marks of their prostrations.
This is how they are pictured in the Torah and the Gospel: like a seed that puts forth its shoot, becomes strong, grows thick, and rises on its stem to the delight of its sowers. So God infuriates the disbelievers through them; God promises forgiveness and a great reward to those who believe and do righteous deeds.”(48:29)
