These snippets from the stories in the Holy Qur’an takes up a large portion of the Holy Qur’an about ¾ of it. These stories are told so as to make firm the heart of the Prophet r.
﴾وَكُلًّا نَّقُصُّ عَلَيْكَ مِنْ أَنبَاءِ الرُّسُلِ مَا نُثَبِّتُ بِهِ فُؤَادَكَ ۚ وَجَاءَكَ فِي هَٰذِهِ الْحَقُّ وَمَوْعِظَةٌ وَذِكْرَىٰ لِلْمُؤْمِنِينَ﴿
“And each [story] We relate to you from the news of the messengers is that by which We make firm your heart. And there has come to you, in this, the truth and an instruction and a reminder for the believers.” [Surah Hud: 120].
It is also to derive lessons from history, lessons for community living, lessons in government and lessons in economy and anything that has to do with human activities in life. And these are the true stories in the Holy Qur’an.
