[41]. Ha-Mim_Al-Sajdah (Prostration) also known as Surah Fussilat [They Are Explained in Detail]: Ayat 044

৪৪. আমি যদি একে অনারব ভাষায় কোরআন করতাম, তবে অবশ্যই তারা বলত, এর আয়াতসমূহ পরিস্কার ভাষায় বিবৃত হয়নি কেন? কি আশ্চর্য যে, কিতাব অনারব ভাষায় আর রসূল আরবী ভাষী! বলুন, এটা বিশ্বাসীদের জন্য হেদায়েত ও রোগের প্রতিকার। যারা মুমিন নয়, তাদের কানে আছে ছিপি, আর কোরআন তাদের জন্যে অন্ধত্ব। তাদেরকে যেন দূরবর্তী স্থান থেকে আহবান করা হয়।

Ayat 44. And if We had sent this as a Qur’an in a foreign language other than Arabic, they would have said: "Why are not its Verses explained in detail (in our language)? What! (A Book) not in Arabic and (the Messenger) an Arab?" Say: "It is for those who believe, a guide and a healing. And as for those who disbelieve, there is heaviness (deafness) in their ears, and it (the Qur’an) is blindness for them. They are those who are called from a place far away (so they neither listen nor understand).

Tafseer of Surah Ha-Mim Al-Sajdah (or Surah Fussilat) Ayat 44. Had Allah sent this as a Qur´an (in the language) other than Arabic, they would have said: "Why are not its verses explained in detail? What! (A Book) not in Arabic and (a Messenger an Arab?" Say: "It is a Guide and a Healing to those who believe; and for those who believe not, there is a deafness in their ears, and it is blindness in their (eyes): They are (as it were) being called from a place far distant!" Cf. 16:103-105; 12:2; etc. It was most natural and reasonable that the Messenger being Arab, the Message should be in his own tongue, that he might explain it in every detail, with the greatest power and eloquence. Even though it was to be for the whole world, its initial exposition was thus to be in Arabic. But if people had no faith and were spiritually deaf or blind, it would not matter in what language it came. Cf. 41:5, and 6:25. They pretended that it was too deep for them, when they meant that they were superior to it! The fact was that by putting themselves in an artificially false position, they rendered themselves impervious to the Message. The voice of Revelation or the voice of conscience sounded to them as if it came from a far-off place! They themselves made themselves strangers to it. 

Hazrat Ibn `Abbas (May Allah be pleased with them) reported: The Messenger of Allah (PBUH) said, "He who does not memorize any part from the Qur'an he is like the ruined house.''  [At-Tirmidhi Hadith # 2913]. 

Lesson: This Hadith means that the heart of that Muslim is devoid of grace of spiritualism and Grace of Allah who does not remember by heart any portion of the Qur'an, in the same way as a deserted house is deprived of inhabitants and Blessings of Allah. What we learn from this is that every Muslim must remember some portion of the Qur'an so that he is safe from the admonition mentioned in this Hadith.
