La ilaha illallahu wahdahu la sharika lah, lahul-mulku wa lahul-hamd, wa Huwa 'ala kulli shay'in Qadir. SubhanAllah, wal-hamdu lillah, wa la ilaha illallah, wallahu Akbar, wa la hawla wa la quwwata illa billahil-'Aliyyil-'Adhim.
There is no deity except Allah, alone, without partner. To Him belongs the dominion and to Him belongs all praise, and He is over all things competent. Glory be to Allah, praise be to Allah, there is no deity except Allah, Allah is the Greatest, and there is no might nor power except with Allah, the Most High, the Most Great.
— Sahih Al-Bukhari · 1154
The Prophet ﷺ said: 'Whoever wakes up at night and says this, then says: O Allah forgive me, or supplicates to Allah, he will be answered. And if he makes wudu and prays, his prayer will be accepted.'
Inna fi khalqis-samawati wal-ardi wakhtilafiil-layli wan-nahari la-ayatin li-ulil-albab. Alladhina yadhkurunallaha qiyaman wa qu'udan wa 'ala junubihim wa yatafakkaruna fi khalqis-samawati wal-ard. Rabbana ma khalaqta hadha batilan subhanaka faqina 'adhaban-nar... (10 versets complets jusqu'à) Ya ayyuhalladhina amanus-biru wa sabiru wa rabitu wattaqullaha la'allakum tuflihun.
Indeed, in the creation of the heavens and the earth and the alternation of the night and the day are signs for those of understanding. Who remember Allah while standing or sitting or lying on their sides and give thought to the creation of the heavens and the earth: 'Our Lord, You did not create this aimlessly; exalted are You, then protect us from the punishment of the Fire.' ... (to) O you who have believed, persevere and endure and remain stationed and fear Allah that you may be successful.
— Al-Imran · 3:190-200
The Prophet ﷺ used to recite these last ten verses of Surah Al-Imran when he woke up at night.
Allahumma inni asbahtu ushhiduka, wa ushhidu hamalata 'arshik, wa mala'ikatak, wa jami'a khalqik, annaka Antallahu la ilaha illa Anta wahdaka la sharika lak, wa anna Muhammadan 'abduka wa rasuluk.
O Allah, I have reached the morning and I call upon You, the bearers of Your Throne, Your angels, and all of Your creation to witness that You are Allah, there is no deity except You, alone, without partner, and that Muhammad is Your servant and messenger.
— Sunan Abu Dawud · 5069
Whoever says it four times in the morning, Allah will free him from the Hellfire.
Allahumma bika asbahna, wa bika amsayna, wa bika nahya, wa bika namutu, wa ilaykan-nushur.
O Allah, by Your leave we have reached the morning, and by Your leave we have reached the evening. By Your leave we live and by Your leave we die, and unto You is the resurrection.
— Sunan At-Tirmidhi · 3391
Supplication that the Prophet ﷺ used to say in the morning.
Asbahna 'ala fitratil-Islam, wa 'ala kalimatil-ikhlas, wa 'ala dini nabiyyina Muhammadin ﷺ, wa 'ala millati abina Ibrahima hanifan Musliman wa ma kana minal-mushrikin.
We have reached the morning upon the fitrah of Islam, upon the word of sincerity, upon the religion of our Prophet Muhammad ﷺ, and upon the way of our father Ibrahim, who was upright, a Muslim, and was not of the polytheists.
— Musnad Ahmad · 3/406

Allahumma ma asbaha bi min ni'matin aw bi-ahadin min khalqik, faminka wahdaka la sharika lak, falakal-hamdu wa lakash-shukr.
O Allah, whatever blessing I have this morning, or any of Your creation has, is from You alone, without partner. So for You is all praise and for You is all thanks.
— Sunan Abu Dawud · 5073
Whoever says this in the morning has fulfilled the gratitude for that day.
Allahumma 'afini fi badani. Allahumma 'afini fi sam'i. Allahumma 'afini fi basari. La ilaha illa Ant. Allahumma inni a'udhu bika minal-kufri wal-faqr, wa a'udhu bika min 'adhabil-qabr, la ilaha illa Ant.
O Allah, grant me health in my body. O Allah, grant me health in my hearing. O Allah, grant me health in my sight. There is no deity except You. O Allah, I seek refuge in You from disbelief and poverty, and I seek refuge in You from the punishment of the grave. There is no deity except You.
— Sunan Abu Dawud · 5090
The Prophet ﷺ never failed to say this supplication in the morning and evening.
