´It was narrated from abu Bakrah that the Prophet said; 'None of you should say:` 'I fasted Ramadan' or 'I prayed Qiyam throughout the whole month."' I do not know whether he dislike self-praise or he said: "Inevitably there will be heedlessness and sleep." (Da 'if)

Explanation & Benefits
Hafiz Muhammad Ameen
(1) This narration is weak. In another weak narration, it is mentioned that the Prophet (sallallahu alayhi wa sallam) said: "Do not say 'Ramadan,' because Ramadan is one of the names of Allah; rather, you may say: 'the month of Ramadan.'" See (Dhakheerat al-‘Uqba: 20/269, 270).
(2) It is understood that there is no harm in using such expressions, as is evident from hadiths: 2100, 2101, 2102, and the authentic hadiths that follow, that it is not appropriate to attribute virtue to oneself; rather, one should attribute it to Allah's granting of success (tawfiq). Also, one should not announce one's good deeds without reason. Good deeds have no value without acceptance, and knowledge of acceptance is with Allah alone; therefore, purification (tazkiyah) can only be from Allah.

Benefits and Issues:
In the Noble Qur’an it is stated: (So do not claim yourselves to be pure; He is most knowing of who fears Him) (An-Najm: 32) — Do not proclaim your own virtues and goodness; He (Allah Ta’ala) knows well those who are righteous.
This hadith is weak.
Therefore, if the intention is not to express one’s own greatness or to declare one’s own purity, then mentioning it as a narration is permissible.
