Shaikh Zayd ibn Hadi al-Madkhli rahimahullah was asked:
Is it from the methodology of the Salaf to praise some of those who oppose the methodology of the Salaf in order to win their hearts, attract them to the methodology of the Salaf, and its influence on its followers?
It is not from the methodology of the Salaf to water down the da’wah to Allah through beautiful praise for those who oppose the People of Sunnah from the people of innovation in their sittings and gatherings, and recommending them in order to win their hearts and win their followers. Rather, then one who wants to win over the disobedient, especially the people of deviation in Aqeedah, in the methodology in struggling in the path of Allah, and in calling to Allah, then let him rely upon the text in the Honorable Quran and the purified Sunnah according to the understanding of the Salaf of the Ummah, putting his trust in Allah, giving advice sincerely. So whoever Allah wants to guide him, He will open his chest to accept the truth and act upon it. Whoever He wills to misguide, He will make his chest narrow and tight, hating the truth and its People.
In truth, the who who does not have admonishments and does not benefit from the purified legislation of Allah, then good is not expected from him nor rectification”
