The Quranic ayats related to Ramadan are found within Surah al-Baqarah which details the meaning of Ramadan and what we should observe during this blessed month.
We should aim to discipline the human appetite and the inclination to indulge in worldly attractions by controlling our indulgences.
We are made up of 2 substances;
1. Matter and material; i.e: the physical body
2. Soul and spirit
Allah has endowed us with guidance and it is up to us to learn to control our animalistic desires.
