The Messenger of Allah (may Allah bless him and grant him peace) said:
“Three persons whose Du’a is never rejected (by Allah) are: the fasting person until he breaks his fast (in another narration, when he breaks fast), the just ruler and the one who is oppressed.”
The Messenger of Allah (may Allah bless him and grant him peace) said:
“Whoever does not give up forged speech and evil actions, Allah is not in need of his leaving his food and drink (i.e. Allah will not accept his fasting.)”
The Messenger of Allah (may Allah bless him and grant him peace) said:
“There is a gate in the Garden called ar-Rayyan which those who fast will enter on the Day of Rising, and none but they will enter it.” It will be said, ‘Where are the fasters?’ They will stand up and none but they will enter it. When they have entered it, it will be closed and no one else will enter it.”
The Messenger of Allah (may Allah bless him and grant him peace) said:
“Do not fast immediately before Ramadan. Fast when you see the new moon and break it when you see it. If cloud obscures it, then complete the thirty days.”
The Messenger of Allah (may Allah bless him and grant him peace) said:
“Beware of suspicion. Suspicion is the most untrue speech. Do not spy and do not eavesdrop. Do not compete with each other and do not envy each other and do not hate each other and do not shun each other. Be slaves of Allah, brothers.”
