(2) Al'ummah ta yarda cewa azumin watan Ramadan wajibi ne, kuma dalilin hakan yana cikin Alqur'ani da Sunnah. Allah ya ce (fassarar ma'anarsa):

(2) The ummah is agreed that fasting the month of Ramadaan is obligatory, the evidence for which is in the Qur’aan and Sunnah. Allaah says (interpretation of the meaning):

“Ya ku waɗanda suka yi imani! An wajabta muku azumi kamar yadda aka wajabta wa waɗanda suka gabace ku, don ku zama masu taqawa.” [Al-Baqarah 2:183] Annabi ﷺ ya ce: “An gina Musulunci a kan abubuwa biyar…” daga cikinsu ya ambaci azumin Ramadan. (Al-Bukhari ne ya rawaito shi, al-Fath, 1/49). Duk wanda ya karya azumin Ramadan ba tare da wani halastaccen uzuri ba, ya aikata babban zunubi mai girma. Annabi ﷺ ya ce, yana bayyana mafarkin da ya gani: “… har na isa dutse, inda na ji muryoyi masu ƙarfi. Na tambaya: ‘Mene ne waɗannan muryoyi?’ Suka ce: ‘Wannan kukan mutanen Wuta ne.’ Sannan aka ɗauke ni [zuwa wani wuri], sai na ga mutane rataye da jijiyoyin dugadugansu, kusurwoyin bakunansu sun yage kuma jini na zuba daga gare su. Na ce: ‘Su waɗannan wane ne?’ Suka ce: ‘Mutanen da suka karya azumi kafin lokacinsa ya yi, watau kafin lokacin buɗa baki.’” (Saheeh al-Targheeb, 1/420).

“O you who believe! Observing al-sawn (the fasting) is prescribed for you as it was prescribed for those before you, that you may become al-muttaqoon (the pious).” [al Baqarah 2:183] The Prophet (peace and blessings of Allaah be upon him) said: “Islam is built on five [pillars]…” among which he mentioned fasting in Ramadaan. (Reported by al-Bukhaari, al Fath, 1/49). Whoever breaks the fast during Ramadaan without a legitimate excuse has committed a serious major sin, The Prophet (peace and blessings of Allaah be upon him) said, describing a dream that he had seen: “… until I was at the mountain, where I heard loud voices. I asked, ‘What are these voices?’ They said, ‘This is the howling of the people of Hellfire.’ Then I was taken [to another place], and I saw people hanging from their hamstrings, with the corners of their mouths torn and dripping with blood. I said, ‘Who are these?’ They said, ‘The people who broke their fast before it was the proper time to do so,’ i.e., before the time of iftaar.” (Saheeh al-Targheeb, 1/420).

Al-Haafiz al-Dhahabi (Allah ya yi masa rahama) ya ce, "Daga cikin muminai an tabbatar da cewa duk wanda ba ya azumin watan Ramadan ba tare da uzuri mai inganci ba, ya fi muni fiye da mazinaci ko mashayi; suna shakkar ko ma shi musulmi ne, kuma suna ɗaukarsa a matsayin mai bidi'a kuma fasiki." Shaikh al-Islam [Ibn Taimiyya] (Allah ya yi masa rahama) ya ce: "Idan mutum ba ya azumin watan Ramadan yana sane da cewa haramun ne amma yana halatta masa yin hakan, to a kashe shi; kuma idan ya yi hakan saboda rashin da'a [amma yana gaskanta cewa haramun ne], to a hukunta shi saboda rashin azumi." (Majmu'u al-Fatawa, 25/265).

Al-Haafiz al-Dhahabi (may Allaah have mercy on him) said, “Among the believers it is well-established that whoever does not fast in Ramadaan without a valid excuse is worse than an adulterer or drunkard; they doubt whether he is even a Muslim at all, and they regard him as a heretic and profligate.” Shaykh al-Islam [Ibn Taymiyah] (may Allaah have mercy on him) said: “If a person does not fast in Ramadaan knowing that it is haraam but making it halaal for himself to do so, kill him; and if he does it because he is immoral [but believes it is haraam], then punish him for not fasting.” (Majmoo’ al-Fataawa, 25/265).
