It was narrated from Samurah bin Jundub that :
the Prophet (ﷺ) said: “(There are) four that are the best of words, and there is no harm for you in which of them begin with: Subhan-Allah, wal-Hamdu-Lillah, wa la ilaha illallah, wa Allahu Akbar (Glory is to Allah, praise is to Allah, none has the right to be worshipped but Allah and Allah is the Greatest).”
حَدَّثَنَا أَبُو عُمَرَ، حَفْصُ بْنُ عَمْرٍو حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنَا سُفْيَانُ، عَنْ سَلَمَةَ بْنِ كُهَيْلٍ، عَنْ هِلاَلِ بْنِ يِسَافٍ، عَنْ سَمُرَةَ بْنِ جُنْدَبٍ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَ “ أَرْبَعٌ أَفْضَلُ الْكَلاَمِ لاَ يَضُرُّكَ بِأَيِّهِنَّ بَدَأْتَ سُبْحَانَ اللَّهِ وَالْحَمْدُ لِلَّهِ وَلاَ إِلَهَ إِلاَّ اللَّهُ وَاللَّهُ أَكْبَرُ ” .
