Loyalty and allegiance to Allah and His Messenger will lead to unity in the Ummah. There will be peace and desire to seek the truth.
On the contrary, loyalty and allegiance towards a group or institution or shaykh or madhab will lead to disunity,violence and madhab fanaticism and this means the quest, the thirst for seeking the truth will be no more.
Alhamdulillah this is the lesson I learnt from IOU Fiqh 101.
Be wise. Stay focused. Seek the truth.
May Allah Guide us all. Ameen
