The dua upon waking up is: 'Al-hamdu lillahil-ladhi ahyana ba'da ma amatana wa ilayhin-nushur' — meaning 'All praise is for Allah Who gave us life after causing us to die, and to Him is the resurrection.' It is the first words a Muslim says each morning.
الْحَمْدُ لِلَّهِ الَّذِي أَحْيَانَا بَعْدَ مَا أَمَاتَنَا وَإِلَيْهِ النُّشُورُ
Al-hamdu lillahil-ladhi ahyana ba'da ma amatana wa ilayhin-nushur.
Meaning: All praise is for Allah Who gave us life after causing us to die, and to Him is the resurrection.
Source: Sahih al-Bukhari #6312This dua begins the day with gratitude, recognizing that waking up is a gift from Allah. Each morning is a new opportunity granted by Allah. The mention of 'resurrection' (nushur) reminds the believer of the Day of Judgment, starting the day with awareness of the Hereafter.
الْحَمْدُ لِلَّهِ الَّذِي أَحْيَانَا بَعْدَ مَا أَمَاتَنَا وَإِلَيْهِ النُّشُورُ
When the Prophet (peace be upon him) woke up from sleep, he would say: 'Al-hamdu lillahil-ladhi ahyana ba'da ma amatana wa ilayhin-nushur.'
