From the lecture entitled al-Thabāt ʿala-al-Sunnah (Steadfastness Upon the Sunnah):
“O brothers, lying is more repulsive than innovation! Lying is more repulsive to the people of the Sunnah than the one who innovates (because) the innovator can be narrated from. The Qadariyyah were narrated from, the Murjīʾah were narrated from, and other than them from the various groups of innovation as long as their innovation does not exit them from the fold of Islām and as long as they were not known for lying.
If someone was considered by the people of Sunnah to be a liar, they would regard him to be from among the people of innovation. This is why Ibn Adī (رحمه الله) compiled approximately twenty-nine chapters about the liars and one chapter for the people of innovation. The people of Sunnah accepted the narrations from the people of innovation who were truthful except those who called (to their innovation).”
