Our noble Shaykh, ʿAbdullāh al-Nahārī gives a detailed explanation of the evils of splitting and differing and the importance of sticking to the Jamāʿah.
The noble shaykh gives a very informative lecture concerning the evils of splitting and differing, drawing upon evidence from the Qurʾān, Sunnah and statements of the Scholars. It is obligatory to know that differing is something which Allāh has decreed and will happen. The people of differing are a people of disobedience, and the people who are enveloped by the Mercy of Allāh are the Jamāʿah. Though they may be separated by land and in their physical bodies, they are one Jamāʿah. However, the people of splitting and differing are a people of disobedience, and though they may be in the same land they will remain divided. It is obligatory upon Ahl al-Sunnah to speak out against innovations and its people, and the only way in which we can we bring about togetherness and unity is by clinging to the rope of Allāh upon the Qurʾān and Sunnah, and upon the understanding of the Salaf.
