Seems like for most the sunnah a moderate path of neither reward or punishment us used for abstaining.
Brother M.I.A,
The term sunnah, which you are referring to, as per the first paragraph of brother Muhammad's post, is actions which the prophet :saws: did which aren't compulsory. But I am wondering if you have read the next paragraph, where the Islamic source of law and guidance that goes together with the Qur'an, is called the sunnah. The term sunnah, has different meanings, depending on which discipline is being referred to, and we have to be clear about what it means when someone uses the term i.e. which of it's meanings they are referring to - not realising these different meanings, can mean one has huge misunderstandings, as well as it being a potential disaster for one's faith. E.g. someone may only know one usage of term sunnah, and think it means only non-compulsory things, such as fasting on Mondays and Thursdays, and so may erroneously come to the conclusion that the prophet's sunnah is optional and doesn't have to be followed, not realising that sunnah used in that way, not referring to a specific act, actually means something different.
The definition of the term sunnah, as being used in this particular thread, from an Islamic legal theory perspective, is: "
Whatever comes from the Prophet :saws:, other than the Quran itself, in the form of his speech, actions and tacit approvals." His speech includes, what he commanded, recommended, permitted, disapproved, or forbade. .
All the Prophets had a sunnah that people had to follow. The prophets were sent by Allah to be role models and examples for human beings, showing us practically how to put the guidance they were sent with into practice in our daily lives, explaining the scriptures, warning against wrong-doing, giving good tidings, and giving additional legislation from Allah. This was inspired and instructed by Allah to them - they didn't make it up. And it went together with, and had to be followed along with, any scripture that Allah gave then, as a mandatory source of law for the faith. Even previous prophets sunnah was compulsory for their followers to follow. Jesus (Isa, peace be upon him) had a sunnah that people should follow:
And when Jesus brought clear proofs, he said, "I have come to you with wisdom and to make clear to you some of that over which you differ, so fear Allah and obey me.(43:63)
Then We sent following their footsteps Our messengers and followed [them] with Jesus, the son of Mary, and gave him the Injeel... (57:27, part)
We know that Allah gave Jesus (alyhissalaam) the Injeel, which was Allah's words, so obeying the Prophet meant listening to him explaining Allah's words, and following whatever else he commanded in respect to the deen as inspired by Allah.
So in this thread, the term sunnah doesn't mean e.g. fard, wajib, sunnah ( ie specific acts which might be compulsory, recommended, permissibe etc), but it refers to a source of evidence and source of law. As the Qur'an is a source of law and source of evidence, so the Sunnah of the Prophet (what the prophet taught along with the Quran, to explain it and complement it) is also mandatory source of law and evidence, that goes hand in hand with the Qur'an, and to reject it is tantamount to rejecting the Prophet, and more.
So this term sunnah, used with the above meaning, is an authority in Islamic law, that goes together with the Qur'an, as we have been commanded to obey the Prophet :saws:, follow his example, and been told by Allah that the Prophet :saws: is our teacher, and that the Prophet :saws: has explained the Book to us. If we reject the sunnah, and reject everything the prophet :saws: said and did, then that means when we say we declare that Muhammad :saws: is the messenger of Allah, that that declaration has not gone past our throats, and it means we go against the Quran where Allah has told the Prophet to teach us, to explain the Quran to us, and told us that we must obey him and follow him. Therefore in rejecting the sunnah, we actually reject part of the Qur'an. Also, the sunnah was divinely inspired to the Prophet :saws: by Allah, so if someone rejects the sunnah, they are rejecting what has come from Allah, and this is rebellion against Allah and his prophet :saws:. In essence, it can completely nullify our faith, and the scholars agree that such a person has left Islam.
The Prophets Sunnah is recorded in the authentic hadeeth, and this is compulsory, obligatory, fard, mandatory, a must, to follow. This is a source of law that goes together hand in hand with the Qur'an, and the Prophet told us that if we stick to the Quran and sunnah we will not go astray, but if we let go of any of them, we will, as alluded to above.
Sounds as orthadox as it gets.
This is not orthodox, this is a fundamental and foundational part of Islam, without which there is no Islam, no matter how much someone may delude themselves in to thinking it is. The prophet :saws:, his companions (may Allah be pleased with him), all the early generations of Muslims, and the main body of Muslims nowadays, all follow the Quran and sunnah, as their two sources of law.
May Allah save us from the rejection of the sunnah, and hence from going astray, ameen.
