Is it established from Imam Ahmad that he disliked the phrase "kufra ni'mah" (ingratitude for a blessing)?

Question:
I read in *al-Durar al-Saniyyah*, Volume One, that Imam Ahmad (may Allah have mercy on him) disliked the phrase "kufra ni'mah" (ingratitude for a blessing). Is this established from him?

Answer:
Yes, indeed. He said that this lightens the matter for people. . But as I mentioned to you, if this is a discussion among scholars and students of knowledge, they say, "This is kufra ni'mah" or "kufra nusr" (ingratitude for support) among themselves, so that one does not take it upon himself to declare people disbelievers of major kufr (disbelief) in the context of deepening understanding of the texts. However, with the common people, you see this as minor shirk (associating partners with Allah) and see it as kufra ni'mah (ingratitude for a blessing), and it does not lead to those who are lax in the matter. Yes, every station has its own discourse. It is obligatory for the student of knowledge to place things in their proper places with wisdom. If you speak before the common people, you do not give them these things that lead them to laxity. And if you speak before the scholars, the scholars have their own specific context. Yes.
