the translation does not look right.
al-naseeha means advice not sincerity
what do you think ?
Assalamu alaykum friend. I found this page that explains the hadith and the meaning of naseeha.
On the authority of Tameem ibn Aus, the Prophet ﷺ said:

Meaning of Naseehah
Al Khattabi and ibn Hajr have stated that there is no word in the Arabic language as comprehensive as naseehah. This word is very difficult to translate in English, and although it’s most often translated as “sincerity”, it has a much deeper meaning to it.
The word naseehah has 2 basic linguistic meanings:
To clean, purify or improve something from unwanted elements
To unite or join something that is scattered or separated
Taking the linguistic meaning and the Quranic usage, al Raaghub al-Isfahaani has given a shareeah definition for naseehah as follows: “Naseehah is a seeking of an action or a statement that contains goodness and improvement for the other person.”
So if you are giving naseehah to someone, you truly wish the best for that person in terms of your intentions and actions.
