Best after Ramadan
The Prophet (S) said: “The best of fasting after the month of Ramadan is the month of Allah, Muharram” Muharram is the first month of the lunar calendar, one of four sanctified and fasting in the month would enable to attain great reward from the Allah. Imam Nawawi said that Muharram is the best month to perform the voluntary fasts .
The 10th of the Muharram is the most sacred of the whole month, for the Prophet (s) directed the Muslims to fast on the Day of Ashura’a (10th Muharram). Abdullah Ibn Abbas narrated that when Prophet (S) migrated to Madeena, the Jews fasted on the day, remembering the emancipation of Musa (A) from the Pharo’ah. Prophet (S) said: “We [Muslims] are more closely rotated to Musa than you.” Abu Qataadah said that the Messenger of Allah was asked about fasting on the day of `Aashura’a, so he said: “It expiates the sins of the previous year.”
According to some hadith, it is ‘more advisable’ that the fast on the 10th Muharram is preceded by another fast, i.e., on the 9th, the reason being to distinguish the fasting of Muslims with Jews . Ibn Abbas narrates Prophet (s) being stating that: “If I live until the next year, I will certainly fast on the ninth day.”
Weak Hadiths on Muharram
“Whoever fasts the first nine days of Muharram, Allah will build for him a dome in the air, which has four doors, the distance of one door to another, is one mile.” This hadith is a false hadith, as explained by Ibn al Jauzi in “Al-Maudhu’at” and Ash Shaukani in “Al-Fawaid Al-Majmu’ah”.
“Whoever fasts on the last day of month Dul Hijja and the first day of month Muharram, it means that he ended the year and began the New Year with fasting. Allah will make these fasts of him as retribution for five years.” The hadith is a false hadith, because there are two liars in its chain of narration, as explained by Ash Shaukani in “Al-Fawaid Al-Majmu’ah”.
“Indeed, Allah has obliged the children of Israel to perform one day fast in a year that is the day of Ashura’a, the tenth day of month Muharram. Therefore, fast on the month of Muharram and give some (delicious food and new clothes) to your family, because this is day when Allah accepted the repentance of Adam -peace be upon him-…” The hadith is a false hadith as explained in Al-Fawaid Al-Majmu’ah
“Whoever fasts for a day on month Muharram, then for one day of his fast, he will get the reward as (the reward of, -ed) thirty days of fasting.” It is false hadith, as explained by Al Albani in “Silsilah Hadith Dhaif”.
Innovations in the month of Muharram
- Believing that Muharram is the month of Bad luck (Nahs)
Some Muslims believe that Muharram is the month of bad luck, thus they fear to hold any kind of events in the month. An impending doom will be the result of any events. This is a kind of Thiyarah (Belief in misfortune), which the prophet (S) has said is shirk (Polytheism) .
- Deep sadness on the death of Hussain bin Ali
The Death of Hussain (r) on Karbala is of course a bitter memory for one who loves Prophet (s) and his family. But it is no reason it to be considered as the mourning day or the day of mass condolence. In many places people switch off the lights, comes out to the street and shouts “O Hussain, O Hussain”. Some stabs and cuts their body with swords, as an embodiment of their deep condolences. But it has nothing to do with the methodology of the Prophet and the pious predecessors.
- Rejoicing the Day of Ashura’a
They make the Day, a day of feast and excitement, while the prophet and companions took it as a day for fasting.
