[49] Surah Al-Hujurat [The Dwellings]: Ayat 009

৯. যদি মুমিনদের দুই দল যুদ্ধে লিপ্ত হয়ে পড়ে, তবে তোমরা তাদের মধ্যে মীমাংসা করে দিবে।  অতঃপর যদি তাদের একদল অপর দলের উপর চড়াও হয়, তবে তোমরা আক্রমণকারী দলের বিরুদ্ধে যুদ্ধ করবে; যে পর্যন্ত না তারা আল্লাহর নির্দেশের দিকে ফিরে আসে। যদি ফিরে আসে, তবে তোমরা তাদের মধ্যে ন্যায়ানুগ পন্থায় মীমাংসা করে দিবে এবং ইনছাফ করবে। নিশ্চয় আল্লাহ ইনছাফকারীদেরকে পছন্দ করেন।

Ayat 9. And if two parties or groups among the believers fall to fighting, then make peace between them both, but if one of them rebels against the other, then fight you (all) against the one that which rebels till it complies with the Command of Allah; then if it complies, then make reconciliation between them justly, and be equitable. Verily! Allah loves those who are equitable.

Tafseer of Surah Al-Hujurat Ayat 49. Al Hujurat (The Chambers) Ayat 10. The Believers are but a single Brotherhood: So make peace and reconciliation between your two (contending) brothers; and fear Allah, that ye may receive Mercy. The enforcement of the Muslim Brotherhood is the greatest social ideal of Islam. On it was based the Prophet's Sermon at his last pilgrimage, and Islam cannot be completely realized until this ideal is achieved. 

Hazrat Anas (May Allah be pleased with him) reported: Messenger of Allah  [SAWW](PBUH) said, "Help your brother, whether he is an oppressor or is oppressed". A man enquired: "O Messenger of Allah! I help him when he is oppressed, but how can I help him when he is an oppressor?'' He  [SAWW](PBUH) said, "You can keep him from committing oppression. That will be your help to him".  [Al-Bukhari Volume 3, Book 43, Hadith Number 624].

Lesson: as mentioned above in Surah Al-Hujurat Ayat 9. And if two parties or groups among the believers fall to fighting, then make peace between them both, but if one of them rebels against the other" This Hadith contains a very comprehensive injunction to eliminate disturbance and tyranny in the Muslim society. It not only ordains helping the oppressed but also encourages people endowed with moral courage to stop the oppressor's oppression. Doing so requires great courage and boldness, but Muslims would be able to do full justice to their duty of wishing well to their fellow Muslims when they develop the moral courage to stop the oppressor from tyranny, or at least protest against it verbally.
