A Brief Reminder To Those Mancunian Non-Muslims Who Genuinely Made a Mistake and Recently Had To Apologise For Associating The Statement ‘ Allaahu Akbar’ With The Atrocities of The Vile Terrorists
Allaah (The Most High) said:
And magnify Him (i.e. Allaah) with all the magnificence, [Allahu-Akbar (Allah is the Most Great)]. [17:111]
The Scholar and well-known explainer of the Qur’aan, Ibn Jareer (rahimahullaah) stated about this verse: ”And exalt your Lord O Muhammad through what He has commanded you to exalt Him, in speech and deeds; obey Him in what He has commanded you (i.e. by fulfilling it) and with regards to what He has forbidden you (i.e. by keeping away from it)”. 
The Scholar and well-known explainer of meanings of the Qur’aan, Muhammad Al-Ameen Ash-Shanqeetee (rahimahullaah), stated about this verse: Exalt [Allaah] with a powerful exaltation. Manifest the greatness of Allah (by) strongly guarding what He has commanded and keeping away from what He has forbidden, and hastening towards everything that pleases Him, (which is) similar to His statement: [لِتُكَبِّرُوا اللَّهَ عَلَىٰ مَا هَدَاكُمْ -That you may magnify Allah for His Guidance to you.  [End of quotes]
The above explanations of the rightly guided scholars clearly manifests the fact that exalting Allaah with [Allaahu Akbar – Allaah is the Greatest] is utilised in obedience to Allaah and not in disobedience. As for the terrorists, they utilise this statement in the name of committing atrocities and crimes against people. So we hope that this affair is clarified for those non-Muslims who genuinely misunderstood this concept. Here are a few links to demonstrate the fact that Islaam is free from the evil and murderous activities of the misguided terrorists.
