In The Name of Allah, The Most Merciful, The Bestower of Mercy.

Al Allaamah Rabee Bin Hadi Al-Madkhali, may Allah preserve him, said:

Loyalty to and enmity against specific individuals, similar to the manner in which the Rawafid (Shiites) exhibit false loyalty to specific members of the Prophet’s family: Shaikh Al-Islam, may Allah have mercy on him, stated in “Minhaj al-Sunnah” (133/5):

“The Rāfidah have adopted a divisive approach regarding the companions of the Messenger, showing loyalty to some while excessively praising them, and harbouring animosity towards others while being extreme in their animosity”.

Many individuals adopt a similar stance towards their leaders, kings, scholars, and elders, resulting in rejecting one another for others besides the companions. You find a proponent of illegal partisanship showing loyalty to so and so, and to those who love him, while showing enmity to so and so, and to those who love him based on other than truth (or without a justified Shariah reason). This is entirely from that splitting and affiliation that Allah and His Messenger have prohibited, as He, the Exalted, stated:

إِنَّ الَّذِينَ فَرَّقُوا دِينَهُمْ وَكَانُوا شِيَعًا لَسْتَ مِنْهُمْ فِي شَيْء

Verily, those who divide their religion and break up into sects (all kinds of religious sects), you (O Muhammad) have no concern in them in the least.
(Al-An’am: 159)
