O you who believe! Fasting is prescribed for you as it was prescribed for those before you, that you may become people having taqwa [Surah al-Baqarah 2:183]
From this ayah we learn that fasting has been made obligatory on us. But a matter which very few of the general people notice, is that here, the wisdom behind the command is mentioned. When Allah commands His believing servants, He usually mentions the command without mentioning the wisdom. However, here the reason for fasting is mentioned. So the wisdom behind fasting is not only to prevent the permissible good things, even though this is an obligation, but this is not the only thing that is required and intended by this fasting. The wisdom is that the Muslim should increase in obedience in the month of fasting and become more obedient than he was before it.
The fasting person should also withhold from sins and acts of disobedience to Him. So withhold from forbidden actions such as backbiting, carrying tales to cause harm to people, false witnesses, lying, and so on, with regard to those forbidden manners that we are all aware of.
Some scholars divide those things with disrupt the fast into two categories. The first category is eating, drinking and sexual intercourse. One must concentrate a great deal on the second category of things which disrupt the fast. People have become used to thinking fasting is from the first category.
Whoever does not abandon falsehood in speech and action, then Allah has no need that he should leave his food and drink.
Every fasting person should examine himself and see: is he just withholding from the non-material things? has he made his manners and behaviour good when the blessed month of Ramadan comes? If one continues to persist in the evil manners which he was upon before Ramadan, then this is not the fasting that is desired and required from the wisdom behind the legislation of this noble month.
Hastening Iftaar and delaying Suhoor
The Prophet would break the fast with 3 dates. Then he would pray the Maghrib prayer and then he would eat again if he found that he needed to eat the evening meal.
