Allāh, the Majestic mentioned in his Noble Qurʾān,
The believers are nothing else than brothers. So make reconciliation between your brothers, and fear Allāh, that you may receive mercy.  (al-Ḥujurāt 49:10) 

“Brotherhood is more precious than anything on the earth…who said so Rabb al-ʿAlamīn….

And He has united their (i.e. believers’) hearts. If you had spent all that is in the earth, you could not have united their hearts, but Allāh has united them. Certainly He is All-Mighty, All-Wise.  (Al-Anfāl 8:63) 

..if we recognise that brotherhood is this precious, then we must be ready to stand up and defend it in the face of every troublemaker and every haughty arrogant individual who tries to ruin it. Why should we stand in their face? Because they are doing the devil’s work!! As Allāh said, ‘The devil is the one who is intent on sowing the seeds of hatred and rancour between you’…so whoever  tries to ruin Islamic brotherhood then we have to stand in his face! Because he is doing the devils work whether he is pleased with this or not!

Why does the Devil want to destroy this brotherhood?

…that is so precious and valuable, brotherhood that if we lack it we will be weak,  brotherhood if we are without out, we will be susceptible, brotherhood if we are without it, we will never achieve anything. The Shayṭān is aware that if there is no brotherhood, there is no community, if there is no brotherhood, there is no cooperation, if there is no brotherhood…there is weakness.”

Personal problems wrecking brotherhood

…many of us may be sitting in the audience today who have a beef with a brother or a problem with a sister and when we are advised ‘Fear Allāh ‘O Brother’ then we say ‘you don’t know what he did to me’ or we reply ‘well that’s the way I feel’ and some of us go further to an affair that is even more dangerous saying ‘this is not the code of the streets’, put that under your shoe ya akhī! Put that under your shoe ya ukhtee! Because we go with the Sunnah wherever it is…have you entered into Islām completely or do you only pick and choose…but when it goes against your soul you resemble the rest of the people of innovation!

Pardoning and forgiving

“A Jewish women brought a poisoned sheep to the Prophet (ṣallallāhu ʿalayhi wa-sallam) and he ate that poisoned sheep…some of the Companions brought that woman to the Messenger  (ṣallallāhu ʿalayhi wa-sallam) and said ‘should we not kill her?’ and he said ‘No’ so who are you  ʿAbdullāh or Amatullāh, when you are asked to forgive you say you are unable? You not only harm that person (who you hold a grudge against) but you harm yourself!
