وَعَنْ عَائِشَةَ قَالَتْ: إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ إِذَا جَلَسَ مَجْلِسًا أَوْ صَلَّى تكلَّم بِكَلِمَاتٍ فَسَأَلْتُهُ عَنِ الْكَلِمَاتِ فَقَالَ:" إِنْ تُكُلِّمَ بِخَيْرٍ كَانَ طَابَعًا عَلَيْهِنَّ إِلَى يَوْمِ الْقِيَامَةِ وَإِنْ تُكُلِّمَ بِشَرٍّ كَانَ كَفَّارَةً لَهُ: سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ لَا إِلَهَ إِلَّا أَنْتَ أَسْتَغْفِرُكَ وَأَتُوبُ إِلَيْكَ ". رَوَاهُ النَّسَائِيّ

Anas told that when anything caused God’s messenger anxiety he would say, “O Living One, O Eternal One, in Thy mercy I seek help.”Tirmidhi transmitted it, saying this is a gharib tradition which is not committed to memory.**Laisa bi-mahfuz is used here. A tradition called mahfuz is one which is considered superior when compared with a shadhdh tradition (cf. p. xii).
