Muslim: im fasting, can you answer these questions about it.

God said in the Quran: (O you who believe! Observing as-Sawm (the fasting) is prescribed for you as it was prescribed for those before you, that you may become al-Muttaqoon (the pious)) The definition of fasting Ramadan: To refrain from food and drink and sexual intercourse and all other specified things from the time of Fajr (dawn) until the time of Maghrib (sun set). The prophet said: (If any of you are fasting, then abstain from ignorant and indecent speech that day; and if anyone curses you or strikes you, then say: I am fasting). You should also protect the tongue (from evil speech and that which is similar). The Messenger of God said: (Whoever does not abandon evil speech and actions, then God is not in need of him having left his food and drink). Benefit from the fast by leaving off smoking, which causes cancer and ulcers; Try to maintain your willpower and leave off smoking in the evening just as you left it during the day. As a result, you will be better off in health as well as financially; That which nullifies the fast :

• Eating and drinking intentionally;
• Intentionally vomitting.
• Menses and post-partum bleeding – even if it occurred just moments before sunset;
• Excreting semen – whether it is as a result of a man kissing his wife, hugging her or masturbating. Then this nullifies the fast and obligates the making up of the fast (of Ramadan) for that day.
• Sexual intercourse That which does not nullify the fast:
• To mistakenly or forgetfully eat and drink; thereby one is not required to make up the fast nor pay a penalty.
• Unintentional vomitting.
• Using a toothbrush and toothpaste.
• Gargling water and sniffing water up the nose and blowing it out, so long as none of this is done excessively.
• To taste food, with the condition nothing passes the throat to the stomach;
• A young or old man kissing his wife so long as it does not lead to sexual intercourse
• Taking a necessary injection so long as it is not nutrition-based, I.e. a substitute for food, etc;
• Taking a bath to cool oneself down or out of thirst and heat or other than this.
