It is also authentically reported that the Messenger of Allah (peace be upon him) said, “If Allah wills to do good to a person, He makes them comprehend Din ‘religion’.” (Agreed upon by Imams Al-Bukhari and Muslim).
This important Hadith shows us the excellence of comprehending Din.
Comprehending religion includes understanding the Qur’an, the Sunnah, and Islam. Islam covers the basics of Shari`ah, Allah’s Ordainment’s, His Prohibitions, a servant’s duty towards Allah and other servants and Allah’s fear, glorification, and watchfulness. In fact, the first step towards attaining knowledge is fearing Allah (Exalted be He), honoring His Sanctities, and watching Him in all deeds.
Whoever does not fear or be aware of Allah (Exalted be He) in their deeds, all their knowledge will be worthless. However, true beneficial knowledge and understanding of Din that leads to happiness is that which instills Allah’s Awe in a Muslim’s heart, directs them to honor Allah’s Sanctities, pushes them to obey Allah’s Orders and abstain from His Prohibitions, and urges them to call to Allah (Exalted be He) and to clarify Shari`ah to people. So, anyone who is granted comprehension in religion in this way, Allah (Exalted be He) has indeed wanted to do them good.
On the other hand, anyone deprived of these blessings will be among the ignorant, misguided and negligent who renounce attaining the knowledge that Allah (Exalted be He) has made obligatory. They will be among those whom Allah (Exalted be He) has not wanted to do good to them. Further, Allah (Exalted be He) talks about Kafirs (disbelievers) who turn away from the purpose of their creation, to teach us that it is our duty, as Muslims, to haste to comprehend religion and ask about any unclear matter.
Allah (Glorified and Exalted be He) says:
“But those who disbelieve turn away from that whereof they are warned.” [Surah Al-Ahqaf, 46: 3]
Allah (Glorified be He) also says:
“And who does more wrong than he who is reminded of the Ayât (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord, but turns away from them, forgetting what (deeds) his hands have sent forth.” [Surah Al-Kahf, 18: 57]
Consequently, it is the duty of a Muslim to seek for attaining knowledge in religion, to attend to, reflect on, and benefit from the Qur’an and pay great attention to, study, apply, and memorize the Sunnah as much as possible. When a person neglects these two basics, it is an indication that Allah (Exalted be He) did not will good for him. They are doomed since their heart is corrupt and deviating from the path to guidance. We ask Allah to protect and keep us away from whatever displeases Him!
Dear Muslims, it is incumbent upon us to learn our religion and know its rulings and to attend to, meditate, reflect on, recite, and apply the Qur’an. In addition, we should give great care to, memorize, apply and study the Sunnah along with asking about ambiguous matters. Muslims should ask those who have more knowledge to find out the correct answer.
Allah (Glorified be He) says: “So ask the people of the Scripture, if you do not know.” [Surah Al-Nahl, 16: 43]
Moreover, a Muslim can attend knowledge lessons and benefit from them and study with other knowledgeable Muslims to benefit from them and add to himself. In this way, a Muslim can attain comprehension of religion and avoid the characteristics of the negligent and heedless.
The Prophet (peace be upon him) said, “If Allah wills to do good to a person, He makes him comprehend the Din.”
