“O Muhammad, you are ill. He said: ‘Yes.’ He said: Bismillahi arqika, min kulli shay’in yu’dhika, min sharri kulli nafsin aw ‘aynin aw hasidin. Allahu yashfika, bismillahi arqika (In the Name of Allah I perform Ruqyah for you, from everything that is harming you, from the evil of every soul or envious eye, may Allah heal you. In the Name of Allah I perform Ruqyah for you). (Using translation from Ibn Mājah 3523)   

أَنَّ جِبْرِيلَ أَتَى النَّبِيَّ ﷺ فَقَالَ أَلَا أَرْقِيكَ يَا مُحَمَّدُ؟ قَالَ «نَعَمْ» قَالَ بِسْمِ اللهِ أَرْقِيكَ مِنْ كُلِّ شَيْءٍ يُؤْذِيكَ وَمِنْ شَرِّ كُلِّ نَفْسٍ وَعَيْنٍ بِسْمِ اللهِ أَرْقِيكَ  

some Bedouin people used to bring us meat, and we did not know whether they had mentioned the Name of Allah (when slaughtering it) or not. The Messenger of Allah said: "Messenger of Allah said: "Mention the Name of Allah and eat." (Sahih ) (Using translation from Nasāʾī 4436)   

أَنَّ نَاسًا مِنَ الْأَعْرَابِ كَانُوا يَأْتُونَ رَسُولَ اللهِ ﷺ بِلُحُومٍ فَقَالُوا يَا رَسُولَ اللهِ إِنَّ نَاسًا مِنَ الْأَعْرَابِ يَأْتُونَا بِلَحْمٍ وَلَا نَدْرِي أَذَكَرُوا اسْمَ اللهِ عَلَيْهَا أَمْ لَا؟ فَقَالَ رَسُولُ اللهِ ﷺ «اذْكُرُوا اسْمَ اللهِ وَكُلُوا»  

I was with Messenger of Allah ﷺ (on the occasion) of 'Id al-Adha. After he had completed the prayer with people, he found that the goats had been slaughtered, whereupon he said: He who slaughtered sacrificial animal before the prayer should slaughter a goat (again) in its stead and he who has not slaughtered he should slaughter it by reciting the name of Allah. (Using translation from Muslim 1960b)  

شَهِدْتُ الْأَضْحَى مَعَ رَسُولِ اللهِ ﷺ فَصَلَّى بِالنَّاسِ فَلَمَّا قَضَى الصَّلَاةَ رَأَى غَنَمًا قَدْ ذُبِحَتْ قَالَ «مَنْ ذَبَحَ قَبْلَ الصَّلَاةِ فَلْيَذْبَحْ شَاةً مَكَانَهَا وَمَنْ لَمْ يَكُنْ ذَبَحَ فَلْيَذْبَحْ عَلَى اسْمِ اللهِ»  

That the Messenger of Allah ﷺ came across 'Umar while he was on his mount, and he was swearing by his father. So the Messenger of Allah ﷺ said: "Verily Allah prohibits you from swearing by your fathers. So let the one who swears, swear by Allah, or be silent." (Using translation from Tirmidhī 1534)  

أَنَّ رَسُولَ اللهِ ﷺ أَدْرَكَ عُمَرَ فِي رَكْبٍ يَحْلِفُ بِأَبِيهِ فَقَالَ «إِنَّ اللهَ يَنْهَاكُمْ أَنْ تَحْلِفُوا بِآبَائِكُمْ حَالِفٌ يَحْلِفُ بِاللهِ أَوْ لِيَسْكُتْ»  

"Whenever the Messenger of Allah entered the toilet, he would say: 'A'udhu Billahi minal-khubthi wa'l-khaba'ith (I seek refuge with Allah from male and female devils).'" (Using translation from Ibn Mājah 298)  

كَانَ رَسُولُ اللهِ ﷺ إِذَا دَخَلَ الْخَلَاءَ قَالَ «أَعُوذُ بِاللهِ مِنَ الْخُبُثِ وَالْخَبَائِثِ»
