Is it necessary to follow Hadith as we follow Quran as because many groups are in Muslim Ummah which are called as Modern-Day Aqlaniyyah (Rationalists), the Modernists, Munkareen Al Hadeeth(the Hadith Rejectors) and the Secularists. It is necessary for us to understand the importance of Quran so let us explain what is the importances of Hadith:
1. Revelation: The Prophet’s sayings and actions were primarily based on revelation from Allah (One True God) and, as such, must be considered a fundamental source of guidance along with Qur’an. Allah in the Qur’an said concerning the Prophet (pbuh) –
“He does not speak on his own, out of his own desire; That is but a Revelation that is revealed to him.” [Quran 53:3-4]
Therefore, the Hadeeth represents a personal source of divine guidance which Allah granted His Prophet (pbuh) which was similar in its nature to the Qur’an itself. The Prophet (pbuh) reiterated this point in one of his recorded statements, “Indeed, I was given the Qur’an and something similar to it along with it.” [Sunan Abu Dawud]
2. Tafseer: The preservation of the Qur’an was not restricted to protecting its wording from change. Was that the case, its meanings could be manipulated according to human desires, while maintaining its wording. However, Allah also protected its essential meanings from change by entrusting the explanation of the meanings of Qur’an to the Prophet (PBUH) himself. Allah states the following in the Qur’an regarding its interpretation:
“(We sent them) with Clear Signs and Books of dark prophecies; and We have sent down unto thee [Muhammad (pbuh)] the Message; that thou mayest explain clearly to men what is sent for them, and that they may give thought.” [Qur’an 16:44]
Therefore, if one is to understand the meanings of Qur’an, he or she must consider what the Prophet (PBUH) said or did regarding it. E.g. in the Qur’an, Allah instructs the believers to offer salaah (formal prayers) and pay zakaah (obligatory charity) in Chapter 2, verse 43. However, in order to obey these instructions correctly, one must study the methodology of the Prophet (PBUH) in this regard. Among his many clarifications concerning Salaah and zakaah, he instructed his followers saying “Pray as you saw me pray,”[ Sahih Al-Bukhari, vol. 1, no. 604.] and he specified that surplus wealth, unused for a year, should be given as zakaah.
3. Laws: One of the primary duties of the Prophet (pbuh) was to judge between people in their disputes. Since his judgements were all based on revelation, as stated earlier, they must be considered a primary source of principles by which judgements are carried out in an Islamic State. Allah also addressed this responsibility in the Qur’an saying:
“O believers obey Allah, obey the Messenger and those in authority among you. If you dispute about anything, refer it to Allah and the Messenger.” [Quran 4:59]
Thus, Hadeeths are essential for the smooth running of the law courts in an Islamic State.
4. Moral Ideal: Since the Prophet (pbuh) was guided by revelation in his personal life, his character and social interactions became prime examples of moral conduct for Muslims until the Last Day. Attention was drawn to this fact in the following verse of Qur’an:
”Surely there is for all of you a good example (of conduct) in the way of Allah’s Messenger.” [Qur’an 33:21]
Consequently, the daily life of the Prophet (pbuh) as recorded in hadeeth represents an ideal code of good conduct.
5. Preservation of Islam: The science of narration, collection and criticism of hadeeth was unknown to the world prior to the era of the Prophet (pbuh). In fact, it was due in part to the absence of such a reliable science that the messages of the former prophets became lost or distorted in the generations that followed them. Therefore, it may be said that it is largely due to the science of hadeeth that the final message of Islam has been preserved in it is original purity for all times. This is alluded to in the Qur’anic verse:
“Indeed, I have revealed the Reminder, I will, indeed, protect it.” [Qur’an 15: 90]
