Read and reflect on verse 1593 from Surah Hud: AND [remember:] out of all the accounts relating to the [earlier] apostles We convey unto thee [only] that wherewith We [aim to] make firm thy heart: ...
وَكُلًّا نَقُصُّ عَلَيْكَ مِنْ أَنْبَاءِ الرُّسُلِ مَا نُثَبِّتُ بِهِ فُؤَادَكَ ۚ وَجَاءَكَ فِي هَٰذِهِ الْحَقُّ وَمَوْعِظَةٌ وَذِكْرَىٰ لِلْمُؤْمِنِينَ
AND [remember:] out of all the accounts relating to the [earlier] apostles We convey unto thee [only] that wherewith We [aim to] make firm thy heart: for through these [accounts] comes the truth unto thee, as well as an admonition and a reminder unto all believers.
