[30].Surah Ar-Rum [The Romans]: Ayat 32

৩২. যারা তাদের ধর্মে বিভেদ সৃষ্টি করেছে এবং অনেক দলে বিভক্ত হয়ে পড়েছে। প্রত্যেক দলই নিজ নিজ মতবাদ নিয়ে উল্লসিত।

Ayat 32. Of those who split up their religion (i.e. who left the true Islamic Monotheism), and became sects, [i.e. they invented new things in the religion (Bid'ah), and followed their vain desires], each sect rejoicing in that which is with it.

Tafseer of Surah Al Rum (The Romans) Ayat 32. Those who split up their Religion, and become (mere) Sects,- each party rejoicing in that which is with itself! A good description of self-satisfied sectarianism as against real Religion. Scholars translated al-Din al-qayyim as "straight usage." Here the meaning is wider, as it includes the whole life, thoughts and desires of man. The "standard Religion," or the Straight Way is thus contrasted with the various human systems that conflict with each other and call themselves separate "religions" or "sects". Allah's standard Religion is one, as God is One.

Hazrat Irbad bin Sariyah (May Allah be pleased with him) reported: One day Messenger of Allah  [SAWW](PBUH) delivered us a very eloquent Khutbah on account of which eyes shed tears and hearts were full of tears. A man said: "O Prophet of Allah, this is as if it were a parting advice. So advise us". He  [SAWW](PBUH) said, "I admonish you to fear Allah, to listen and obey even if an Abyssinian slave is appointed as your leader. Because whosoever among you shall live after me, will see much discord. So hold fast to my Sunnah and the examples of the Rightly-Guided Caliphs who will come after me. Adhere to them and hold to it fast. Beware of new things (in Deen) because every Bid’ah is a misguidance". [Abu Dawud Hadith # 4607 and At-Tirmidhi Hadith # 2676]. 

Lesson : as mentioned above in Surah Ar-Rum [The Romans] Ayat 32. “those who split up their religion (i.e. who left the true Islamic Monotheism), and became sects, [i.e. they invented new things in the religion (Bid'ah), and followed their vain desires], each sect rejoicing in that which is with it” This Hadith stresses piety, obedience to the leader, following in the footsteps of the Prophet  [SAWW](PBUH) and the first four noble caliphs. It strictly forbids innovation in Deen. This Hadith also reveals the prediction of the Prophet (PBUH) that the Muslim Ummah will become a victim of dissension. He also prescribed the right means to counteract it. The remedy that he has proposed for this problem is that Muslims should never deviate from the path laid for them by him and his righteous successors. This is the touchstone for discovering the truth from the mess of different views. All the troubles of Muslims would come to an end if they accept this as the one singular criterion of right and wrong.
