The du’a that the Prophet (ﷺ) taught to his daughter, Fatimah.
This du‘a was narrated in a sahih hadith from Anas ibn Malik (may Allah be pleased with him), who said: The Prophet (blessings and peace of Allah be upon him) said to Fatimah: “What could prevent you from listening to the advice I give you? You should say when morning comes and when evening comes:
يَا حَيُّ يَا قَيُّومُ بِرَحْمَتِكَ أَسْتَغِيثُ أَصْلِحْ لِي شَأْنِي كُلَّهُ وَلَا تَكِلْنِي إِلَى نَفْسِي طَرْفَةَ عَيْنٍ
Ya Hayyu ya Qayyum, bi rahmatika astaghith, aslih li shani kullahu, wa la takilni ila nafsi tarfat ‘ayn (O Ever-Living, O Self-Sustaining and All-Sustaining, by Your mercy I seek help; rectify all my affairs and do not leave me in charge of my affairs even for the blink of an eye).” (Narrated by an-Nasai in as-Sunan al-Kubra (6/147) and in ‘Amal al-Yawm wa’l-Laylah (no. 46); by al-Hakim in al-Mustadrak (1/730); by al-Bayhaqi in al-Asma’ was-Sifaat (112), and others.)
Al-Mundhiri said in at-Targhib wa’t-Tarhib (1/313): Its isnad is sahih. Shaykh al-Albani said in as-Silsilah as-Sahihah (no. 227): its isnad is hasan.
Few additional du’a were mentined in the lecture:

Abu Bakr (may Allah be pleased with him) reported: He said to the Messenger of Allah (peace and blessings be upon him), “O Messenger of Allah, teach me a supplication to say in my prayers. The Prophet (peace and blessings be upon him) said, “Say:
اللَّهُمَّ إِنِّي ظَلَمْتُ نَفْسِي ظُلْمًا كَبِيرًا وَلَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ فَاغْفِرْ لِي مَغْفِرَةً مِنْ عِنْدِكَ وَارْحَمْنِي إِنَّكَ أَنْتَ الْغَفُورُ الرَّحِيمُ
O Allah, I have wronged myself with great wrongs and none forgives sin but You, so forgive me and have mercy upon me. Verily, You alone are the Forgiving, the Merciful.”

The Prophet’s (ﷺ) Most Repeated Du’a
Shahr bin Hawshab (may Allah be pleased with him) said: “I said to Umm Salamah (may Allah be pleased with her) ‘O Mother of the Believers! What was the supplication that the Messenger of Allah (blessings and peace of Allah be upon him) said most frequently when he was with you?” She said: ‘The supplication he said most frequently was:
يَا مُقَلِّبَ الْقُلُوبِ ثَبِّتْ قَلْبِي عَلَى دِينِكَ
Yā Muqallibal-qulūb, thabbit qalbī `alā dīnik
(“O Changer of the hearts, make my heart firm upon Your religion.”)
She said: ‘So I said: “O Messenger of Allah, why do you supplicate so frequently: ‘O Changer of the hearts, make my heart firm upon Your religion.’ He said: ‘O Umm Salamah! Verily, there is no human being except that his heart is between Two Fingers of the Fingers of Allah, so whomsoever He wills He makes steadfast, and whomever He wills He causes to deviate.’”
