My friend (the Messenger of Allah, may the peace and blessings of Allah be upon him) has instructed me to do three things
Abu Huraira, may Allah be pleased with them, reported. My friend (the Messenger of Allah, may the peace and blessings of Allah be upon him) has instructed me to do three things:
To fast three days during every month, to perform two rak'ahs of the forenoon prayer, and observing Witr prayer before going to bed.
This commandment was not for Abu Hurayrah, may Allah be pleased with him, in particular as it is apparent, but he transmitted it to the other believing men and women.
It is one of the commandments from which the Muslim learns firmness and determination and to force himself to walk on the path of Allah the Almighty; to train the soul to do what it dislikes, to discipline it, to deter it from indulging in the lusts and preferring the laziness.
Fasting three days of each month is a Prophetic Sunnah followed by all the righteous except for an excuse. It is the minimum period to fast during all the months except the month of Sha'baan; the frequent fasting during it is more desirable than the other months. Fasting three days of each month is equivalent to fasting all the year.
Because one will receive ten folds of reward for every good deed, in other words every day of the three days equals one third of the month. If one continued to fast the three days every month, he is like the one who fasts for the whole of the month.
Please be informed that the reward is contingent on sincerity in the deed, perhaps one will do an simple deed according to his perspective and then be rewarded amply, and vice versa.
As for the Duha prayer it is virtuous and entails great rewards, it resembles the night prayer that is held while people are sleeping; the sincerity in both of these prayers is often available and the reward is contingent.
Its time begins when the sun rises the distance of one or two spears and ends before noon time.
The minimum portion to be performed of the Duha prayer are the two rak'ahs, one may suffice with two rak'ahs, or continue to pray twelve rak'ahs.
Please be informed that the prayer of the Duha helps the repentant to renew the repentance and to rectify the intention, to be free from negligence and break the control of the lusts.
As for the Witr prayer, it is a confirmed Sunnah. The Muslim should not leave it especially before going to bed.
It is a confirmed Sunnah, whether it is to be performed before or after sleep. Every Muslim is well aware of what suits his conditions (including the time of the voluntary prayers).
The time for Witr begins after the 'Isha' prayer and extends to the appearance of the true dawn.
He who performed the Witr prayer at the beginning of the night, and then he liked to pray voluntarily, let him pray whatever he wants, but he shall not pray the Witr prayer again, because the Messenger of Allah (may the peace and blessings of Allah be upon him) said: " There should not be two witrs in one night."
