（2）乌玛一致认为，斋戒斋月是义务的，其依据见于《古兰经》和圣训。安拉说（词义的诠释）：

(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):

“噢，信道的人们啊！封斋已为你们规定，正如前人已被规定一样，以便你们敬畏（养成敬畏）。”［黄牛章 2:183］先知（愿安拉的平安与祝福降临他）说：“伊斯兰教建立在五件事之上……”其中提到了斋月的斋戒。（由布哈里记录，《法特赫》，1/49）。凡在斋月中无合法理由而破斋者，即犯了严重的大罪。先知（愿安拉的平安与祝福降临他）在描述他所见的一个梦时说：“……直到我来到一座山前，听到大声的喧哗。我问：‘这些声音是什么？’他们说：‘这是火狱居民的哀嚎。’随后我被带到另一处，看见有人被倒挂着，腿筋被挂住，嘴角被撕裂，鲜血直流。我问：‘这些是什么人？’他们说：‘是那些在未到开斋的正确时间前就破斋的人，即在开斋时间到来之前就破斋的人。’”（《沙希赫·泰尔吉布》，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).

阿勒-哈菲兹·阿尔-达哈比(愿安拉怜悯他)说:"�signature信士们普遍认定,无正当理由不封斋的人,比通奸者或醉酒者更坏;人们怀疑他是否还算穆斯林,并视他为异端和放荡之人。"伊斯兰导师伊本·泰米叶(愿安拉怜悯他)说:"如果一个人明知封斋哨月是haraam(禁止的),却为自己将其视为halaal(允许的)而不封斋,就杀掉他;如果他因放纵而不封斋(但仍相信其为禁止的),那就因他不封斋而惩罚他。"(《穆杰穆尔·法塔瓦》,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).
