The Prophet ﷺ called the Salamander, a mischief-doer. I have not heard him ordering that it should be killed. Saʿd bin Waqqas claims that the Prophet ﷺ ordered that it should be killed.  

أَنَّ النَّبِيَّ ﷺ قَالَ لِلْوَزَغِ الْفُوَيْسِقُ وَلَمْ أَسْمَعْهُ أَمَرَ بِقَتْلِهِ وَزَعَمَ سَعْدُ بْنُ أَبِي وَقَّاصٍ أَنَّ النَّبِيَّ ﷺ أَمَرَ بِقَتْلِهِ  

I did not hear that he had commanded to kill them.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لِلْوَزَغِ الْفُوَيْسِقُ زَادَ حَرْمَلَةُ قَالَتْ وَلَمْ أَسْمَعْهُ أَمَرَ بِقَتْلِهِ  

Yahya related to me from Malik from Nafi from Safiyya bint Abi Ubayd from A'isha and Hafsa, the wives of the Prophet ﷺ that the Messenger of Allah ﷺ said, "It is not halal for a woman in mourning for someone who has died, if she trusts in Allah and the Last Day, to abstain from adornment for more than three nights, except for a husband."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَحِلُّ لاِمْرَأَةٍ تُؤْمِنُ  

The Prophet ﷺ called the Salamander, a mischief-doer. I have not heard him ordering that it should be killed. Saʿd bin Waqqas claims that the Prophet ﷺ ordered that it should be killed. (Using translation from Bukhārī 3306)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لِلْوَزَغِ فُوَيْسِقٌ وَلَمْ أَسْمَعْهُ أَمَرَ بِقَتْلِهِ  

I did not hear that he had commanded to kill them. (Using translation from Muslim 2239)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لِلْوَزَغِ فُوَيْسِقٌ قَالَتْ وَلَمْ أَسْمَعْهُ أَمَرَ بِقَتْلِهِ  

[Machine] Aisha, the wife of the Prophet Muhammad ﷺ , informed him that the Messenger of Allah ﷺ said to the gecko, "You are annoying" and I did not hear him command to kill it.  

أَنَّ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ أَخْبَرَتْهُ أَنَّ رَسُولَ اللهِ ﷺ قَالَ لِلْوَزَغِ فُوَيْسِقٌ وَلَمْ أَسْمَعْهُ أَمْرَ بِقَتْلِهِ
