[Machine] I heard the Messenger of Allah ﷺ say, "Allah does not look at the prayer of a servant who does not straighten his back during his bowing and prostration."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «لَا يَنْظُرُ اللهُ إِلَى صَلَاةِ عَبْدٍ لَا يُقِيمُ ظَهْرَهُ فِي رُكُوعِهِ وَسُجُودِهِ»  

[Machine] "I used to mix clay in the city when a scorpion bit me, then the Messenger of Allah came to me and recited a protection supplication until I was cured."  

«كُنْتُ أَخْلِطُ الطِّينَ بِالْمَدِينَةِ فَلَدَغَنِي عَقْرَبٌ فَأَتَانِي رَسُولُ اللهِ ﷺ فَعَوَّذَنِي حَتَّى بَرَأْتُ»
