Hadhrat Ayyub (Radhiyallahu anh) reports that the Messenger of Allah (peace be upon him) said,
“Whoever fasts Ramadan and follows it with six days from Shawwal it is as though he fasted the entire year.” [Muslim, Abu Dawud, Tirmidhi, and Ibn Majah; Ahmad transmitted it from Jabir, Muntaqa]
Hadhrat Thawban (R A) reports that the Messenger of Allah (blessings and peace be upon him,) said,
“Whoever fasts Ramadan, after which six days after Eid, it’s miles an entire 12 months. Whoever does a terrific deed shall have ten instances its reward.” [Ibn Majah, Muntaqa]
1. Primarily based in this, most of the scholars, including the Ahnaf, Shawafe`, and Hanabilah school, have held that it is endorsed to have soum (fast) six days of the month of Shawwal. [Radd al-Muhtar; Mughni al-Muhtaj Shah al-Minhaj; Kashshaf al-Qina`]
2. It’s far approved to fast six days of shawwal one after the other for the duration of the month, or sequentially together , after Eid al-Fitr.
3. It’s prohibitively undesirable (Makrooh) to fast on the day of Eid and sinful. [Radd al-Muhtar]
4. The Shawafe’ and Hanabila school of thought says that it’s far superior to make the six fasts together [Minhaj, Ghayat al-Muntaha]. Khatib al-Shirbini explains the reasoning as being,
“with a view to hasten to do the good deed, and due to the issues inevitable in delaying,”
Inclusive of turning into lazy and not truely pleasant this sunnah ultimately, although he points out that the sunnah is fulfilled through both consecutive and non-consecutive fasting of six days in Shawwal. [Mughni al-Muhtaj]
The later Hanafi fuqaha differed as to that’s higher, fasting the six days together or individually , though neither is makrooh and each fulfill the sunnah. [Radd al-Muhtar]
but, for those Muslim brothers and sisters who have fear that they won’t be able to fast if they delay it because of laziness or any other reasons they could fast right after Eid and they could fast 6 days of shawal right after Eid.
Sayyiduna Abu Hurayra (Allah be thrilled with him) narrated that the holy Prophet (Peace be upon him) stated,
“The strong believer is better and more cherished to Allah than the weak believer, though there is right in each. Be eager for that which advantages you. trust upon Allah and don’t assume yourself incapable…” [Muslim:4816, Ibn Majah:76, Ahmad:8436]
Imam Nawawi (Allah have mercy on him) defined that the ‘energy’ in this hadith refers to, “One’s determination and potential in matters of the following life.”
