Why should we read the Holy Quran daily? What does the Holy Quran teach us?
Straight away for Barakat/barakah. Secondly, you gain a deeper insight every time you read an aayat with understanding. Every few years situations keep changing but the Quran is always ready to answer based on your situation and circumstances. Thirdly by reading we follow the sunnah of Rasulallah Sallallahu alaihi wasallam who said read and the Quran itself says Quran al fajr, so before or after fajr do take time to read, and his practice was after Isha not to meet or talk to anyone but recite Quran then sleep. Reading he said is better than reciting without looking, so even if you recite its better to have Quran open in front of you.
