faith and belief (iman)

وَإِذْ أَوْحَيْتُ إِلَى ٱلْحَوَارِيِّـۧنَ أَنْ ءَامِنُوا۟ بِى وَبِرَسُولِى قَالُوٓا۟ ءَامَنَّا وَٱشْهَدْ بِأَنَّنَا مُسْلِمُونَ

And [remember] when I inspired to the disciples, "Believe in Me and in My messenger [i.e., Jesus]." They said, "We have believed, so bear witness that indeed we are Muslims [in submission to Allāh]."

فَأَمَّا مَن تَابَ وَءَامَنَ وَعَمِلَ صَـٰلِحًا فَعَسَىٰٓ أَن يَكُونَ مِنَ ٱلْمُفْلِحِينَ

But as for one who had repented, believed, and done righteousness, it is expected [i.e., promised by Allāh] that he will be among the successful.

رَّبَّنَا ٱكْشِفْ عَنَّا ٱلْعَذَابَ إِنَّا مُؤْمِنُونَ

[They will say], "Our Lord, remove from us the torment; indeed, we are believers."

وَصَدَّقَ بِٱلْحُسْنَىٰ

And believes in the best [reward],
