Are the remembrances (dhikr) that I regularly observe in the morning and before sleep authentic?

The validity of the mentioned adhkar (remembrances) varies:

"Subhanakallahumma wa bihamdika..." (Glory be to You, O Allah, and with Your praise...): Narrated concerning the expiation for gatherings, and its chain of narration is hasan (good). "Allahumma anta Rabbi la ilaha illa anta wa 'alaika tawakkalt..." (O Allah, You are my Lord, there is no god but You, and upon You I have relied...): Da'if (weak). "Allahumma inni asbahtu minka fi ni'matin wa 'afiyatin wa satr..." (O Allah, I have awoken from You in blessing, health, and concealment...): Mawdu' (fabricated). "Allahumma ma asbaha bi min ni'matin..." (O Allah, whatever blessing has come to me...): There is a difference of opinion regarding its authentication and weakening. The last two verses of Surah Al-Baqarah: Their mention is not specifically reported in the adhkar of morning, evening, and sleep, but reciting them at night is sufficient. The concluding verses of Surah At-Tawbah ("Laqad ja'akum rasul..." - There has certainly come to you a messenger...): Their recitation in the morning and evening is mentioned in a very weak hadith. "Hasbiyallahu la ilaha illa Huwa, 'alaihi tawakkaltu wa Huwa Rabbu'l-'Arshi'l-'Azim" (Sufficient for me is Allah, there is no god but Him; upon Him I have relied, and He is the Lord of the Great Throne): There is a difference of opinion regarding the authentication of its recitation seven times in the morning and evening. "A'udhu bi kalimatillahit-tammaati min ghadabihi wa 'iqabihi..." (I seek refuge in the perfect words of Allah from His wrath and His punishment...): This is from the adhkar for fear in sleep. Seeking refuge from every devil and harmful creature: This is not specific to morning, evening, and sleep, but rather the Prophet (peace be upon him) used to seek protection for Al-Hasan and Al-Husayn with it. Adhkar for sleep: What is reported from them is the recitation of the Mu'awwidhat (Surahs Al-Ikhlas, Al-Falaq, An-Nas) and Ayat Al-Kursi, and the remembrance: "Allahumma 'alimal-ghaibi wash-shahadah, fatiras-samawati wal-ard, rabba kulli shai'in wa malikah..." (O Allah, Knower of the unseen and the seen, Creator of the heavens and the earth, Lord of everything and its Sovereign...): And it is to be said when one awakes, when one enters the evening, and when one goes to bed.

Specific times should not be designated for the recitation of particular surahs unless there is legal evidence (from the Sharia).
