عَنْ سَمُرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَفْضَلُ الْكَلَامِ بَعْدَ الْقُرْآنِ أَرْبَعٌ وَهِيَ مِنَ الْقُرْآنِ لَا يَضُرُّكَ بِأَيِّهِنَّ بَدَأْتَ سُبْحَانَ اللَّهِ وَالْحَمْدُ لِلَّهِ وَلَا إِلَهَ إِلَّا اللَّهُ وَاللَّهُ أَكْبَرُ
It is narrated from Sayyiduna Samurah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: After the Noble Qur’an, four words are the most excellent speech, and these too are from the Noble Qur’an itself. So whichever word you wish to begin with, it will make no difference. These four words are: Subhan Allah (Glory be to Allah), Alhamdulillah (All praise is due to Allah), La ilaha illallah (There is no god but Allah), and Allahu Akbar (Allah is the Greatest).
