The following is a compilation of the top hadith on fasting to guide you on the right path and ensure you follow the instructions of Allah Almight accordingly during this Holy month.
On the authority of Abu Huraira, peace and blessings of Allah be upon him, said that the Prophet (peace and blessings be upon him) said: Whoever fasts during Ramadan with faith and seeking his reward from Allah will have his past sins forgiven. Whoever prays during the nights in Ramadan with faith and seeking his reward from Allah will have his past sins forgiven. And he who passes Lailat al-Qadr in prayer with faith and seeking his reward from Allah will have his past sins forgiven (Bukhari, Muslim).
Abu Huraira also said: If anyone omits his fast even for one day in Ramadan without a concession or without being ill, then if he were to fast for the rest of his life he could not make up for it (Bukhari).10
Abu Huraira related that the Prophet said: Allah The Most Gracious and The Most Merciful said: “Every deed of man will receive ten to 700 times reward, except Siyam (fasting), for it is for Me and I shall reward it (as I like). There are two occasions of joy for one who fasts: one when he breaks the fast and the other when he will meet his Lord” (Muslim).
Abu Huraira related that Rasulullah said: Many people who fast get nothing from their fast except hunger and thirst, and many people who pray at night get nothing from it except wakefulness (Darimi).4
The right time to start fasting
Ibn Umar, pbuh narratd that that the Prophet said: Do not start fasting unless you see the new moon, and do not end fasting until you see it. If the weather is cloudy then calculate when it should appear (Bukhari, Muslim).
The Suhoor meal (which is eaten before dawn)
Anas related that Rasulullah said: Take the Suhoor meal, for there is blessing in it (Bukhari, Muslim).
