i hope this finds you well InshAllah.

if you wish to earn the reward that is specifically for fasting Ayaam al-Beed, which the Prophet (peace and blessings of Allaah be upon him) urged us to do, you should find out the timings according to the lunar calendar and fast according to it.

And it is starting tomorrow Monday 25^th  tues  26^th and Wednesday 27^th  InshAllah

Be many to practice this Sunnah and may Your reward be great!!

The virtues of fasting are immense, and a number of saheeh ahaadeeth state this, such as the following:

Fasting is something which is just for Allaah, and Allaah will give multiple rewards without measure for it. The hadeeth says: “[Allaah says:] Fasting is Mine and it is I Who give reward for it.” (Al-Bukhaari, Fath, no. 1904)

“In Paradise there is a gate called al-Rayyaan, through which those who fast will enter, and no-one else will enter through it. After they have entered, it will be locked and no-one else will enter it.” (Al-Bukhaari, Fath, no. 1797).

What is meant by al-Ayaam al-Beed is the 13th, 14th, and 15th of each lunar month, because Allaah says (interpretation of the meaning): “They ask you about the new moons. Say: These are signs to mark fixed periods of time for mankind and for the pilgrimage…” [al-Baqarah 2:189]. 

It was narrated that Abu Hurayrah (may Allaah be pleased with him) said: “My close friend [the Prophet (peace and blessings of Allaah be upon him)] advised me to do three things which I will not give up until I die: fasting three days of each month, praying Duha, and sleeping after Witr. Narrated by al-Bukhaari, 1124; Muslim, 721. 

. 

The prayer (du’aa’) of the fasting person will not be refused.” (Reported by al-Bayhaqi, 3/345; see also al-Silsilah al-Saheehah, 1797)

“The one who fasts has two joys: the joy of breaking his fast and, when he meets his Lord, the joy of having fasted.” (Reported by Muslim, 2/807)

“Whoever fasts one day for the sake of Allaah, Allaah will keep his face seventy years’ distance away from the Fire because of it.” (Reported by Muslim, 2/808)

your Reminder Fatima who love you all for the sake of Allah
