[39].Surah Al-Zumar [The Groups]: Ayat 45

৪৫. যখন খাঁটিভাবে আল্লাহর নাম উচ্চারণ করা হয়, তখন যারা পরকালে বিশ্বাস করে না, তাদের অন্তর সংকুচিত হয়ে যায়, আর যখন আল্লাহ ব্যতীত অন্য উপাস্যদের নাম উচ্চারণ করা হয়, তখন তারা আনন্দে উল্লসিত হয়ে উঠে।

Ayat 45. And when Allah Alone is mentioned, the hearts of those who believe not in the Hereafter are filled with disgust (from the Oneness of Allah) and when those (whom they obey or worship) besides Him [like all false deities other than Allah, it may be a Messenger like 'Iesa (Jesus) ­ son of Maryam (Mary), 'Uzair (Ezra), an angel, a pious man, a jinn, or any other creature even idols, graves of religious people, saints, priests, monks, etc.] are mentioned, behold, they rejoice!

Tafseer of Surah Al Zumar Ayat 45. When Allah, the One and Only, is mentioned, the hearts of those who believe not in the Hereafter are filled with disgust and horror; but when (gods) other than He are mentioned, behold, they are filled with joy! To evil ones, the mention of the exclusive service of Good is hateful: they only rejoice when other motives are added, e.g., personal indulgence, ancestral custom, and numerous things in life which compete with Allah's Law in this world (Cf. 40:12).

Hazrat Abdullah bin Masud (May Allah be pleased with him) reported: Messenger of Allah [SAWW](PBUH) said, "Never a Prophet had been sent before me by Allah to his people but he had, among his people, (his) disciples and companions, who followed his ways and obeyed his command. Then there came after them their successors who proclaimed what they did not practice, and practiced what they were not commanded to do. And (he) who strove against them with his hand is a believer; he who strove against them with his heart is a believer; and he who strove against them with his tongue is a believer; and beyond that there is no grain of Faith". [Muslim Book 01, Chapter 21, Hadith # 081]

Lesson: as mentioned above in Surah Al-Zumar Ayat 45 “those (whom they obey or worship) besides Him [like all false deities other than Allah” This Hadith contains a very important prescription to prevent the Muslim society from all things which are forbidden in Islam. So long as Muslims adhered to it and ceaselessly and fearlessly performed their obligation of enjoining the right and forbidding the wrong, their society was largely safe from many evils and sins.
