Hadith 8666
عَنِ النُّعْمَانِ بْنِ بَشِيرٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ أَلَا وَإِنَّ سُبْحَانَ اللَّهِ وَالْحَمْدُ لِلَّهِ وَلَا إِلَهَ إِلَّا اللَّهُ وَاللَّهُ أَكْبَرُ هُنَّ الْبَاقِيَاتُ الصَّالِحَاتُ
It is narrated from Sayyiduna Nu’man bin Bashir (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Beware! These four words are everlasting good deeds: Subhan Allah, Alhamdulillah, La ilaha illallah, and Allahu Akbar.
