Words to Say When Distressed

أَسْمَاءَ ابْنَةِ عُمَيْسٍ قَالَتْ عَلَّمَنِي رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ كَلِمَاتٍ أَقُولُهُنَّ عِنْدَ الْكَرْبِ ‏ "‏ اللَّهُ اللَّهُ رَبِّي لاَ أُشْرِكُ بِهِ شَيْئًا ‏"‏ ‏.‏

It was narrated that Asma’ bint ‘Umais said: “The Messenger of Allah (ﷺ) taught me some words to say at times of distress: Allah! Allahu Rabbi la ushriku bihi shay’an (Allah, Allah is my Lord, I do not associate anything with Him).” (Sahih)
