What is meant by White Days?
The white days are 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].
So the timing of certain acts of worship and the ‘iddah (waiting period for women who have been divorced or widowed, etc.) are worked out according to the lunar months of the Hijri or Islamic calendar
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)
- “There is nothing equivalent to fasting.” (Al-Nisaa’i, 4/165; see also Saheeh al-Targheeb, 1/413)
- “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)
- Fasting will be an intercession for the slave on the Day of Resurrection, when it will say: “O Lord, I stopped him from eating and drinking during the day, so let me intercede for him.” (Reported by Ahmad, 2/174; al-Bayhaqi classed its isnaad as hasan in al-Mujtama’, 3/181; see also Saheeh al-Targheeb, 1/411).
- “Fasting is a protection and a strong fortress against the Fire.” (Reported by Ahmad, 2/402; see also Saheeh al-Targheeb, 1/411 and Saheeh al-Jaami’, 3880)
- “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)
- “Whoever fasts a day seeking the pleasure of Allaah and then dies [i.e. that is the last thing he does] will enter Paradise.” (Reported by Ahmad, 5/391; see also Saheeh al-Targheeb, 1/412)
- “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).
