The Messenger of Allah ﷺ said to me: May I not teach you phrases which you utter in distress? (These are:) "Allah , Allah is my Lord, I do not associate anything as partner with Him."
لِي رَسُولُ اللَّهِ ﷺ أَلاَ أُعَلِّمُكِ كَلِمَاتٍ تَقُولِينَهُنَّ عِنْدَ الْكَرْبِ أَوْ فِي الْكَرْبِ اللَّهُ اللَّهُ رَبِّي لاَ أُشْرِكُ بِهِ شَيْئًا
