Fasting, therefore is an institution designed for educating the soul and casting it in an Islamic evolutionary mould.
There are numerous Hadiths which guide a fasting Muslim towards divine bliss. Imam Ali ibn Abi-Talib (a.s.), quoting his cousin the Holy Prophet (s.a.w.), says:
"Whoever fasts during the month of Ramadhan out of faith and seeking Allah's pleasure and guards his ears, eyes and tongue from harming people, Allah will accept his fasting, forgive his past sins...,,*
Imam Muhammad al-Baqir (a.s.) relates the Prophet's advice to Jabir ibn Abdullah:
"o Jabir, whoever, fasts the days of Ratnadh an, stands for prayers in parts of its nights, guards his/her sexual desires, reins in his/her tongue, lowers his/her gaze and injures, not the feelings of others, will become free of sins as on the day he/she was born." *
Imam Ja'far as-Sadiq (a.s.), on the authority of his illustrious forefathers, quotes his noble ancestor Prophet Muhammad (s.a.w.) as follows:
"If a fasting person when abused, replies peace be upon you I will not abuse as you do, the Lord, the Exalted and Most High, says, By fasting, My servant has saved himself from the evil of My (other) servant, I grant him refuge against the fire." *
* Ahmad i bn Han bal and the compilers of Sunan have narrated the above with slight difference.
