“I used to spend the night at the door of the Prophet ﷺ, so that I may give him his water for Wudu', and I would hear him, for a long period of the night, saying: ‘Allah hears the one who praise Him (Samiʿ Allāhu liman ḥamidah).’ And I would hear him, for a long period saying: ‘All praise is due to Allah, Lord of the all that exists. (Al-ḥamdulillāhi rabbil-ʿālamīn).’”  

كُنْتُ أَبِيتُ عِنْدَ بَابِ النَّبِيِّ ﷺ فَأُعْطِيهِ وَضُوءَهُ فَأَسْمَعُهُ الْهَوِيَّ مِنَ اللَّيْلِ يَقُولُ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ وَأَسْمَعُهُ الْهَوِيَّ مِنَ اللَّيْلِ يَقُولُ الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ
