Quran is best book to recite, read, and understand it's verses. It is eternal voice of Allah's, blessings on all humans, send via supreme prophet Mohammad saww. Who is finnal messenger to spread pity, love, peace, generosity, equality. I am of opinion that humanity is one, same blood rushes in every one's arterial and venous system, All human beings are one ,then no space remains for hate, love can bring stars from heavens and valuing lives will take one horizons. I prefer all books spreading love and unity but reject those books or platforms which perpetuate hate.Add professional books related also. Regards.
