Umm Sharik told that God’s messenger ordered geckos to be killed, saying the gecko blew on Abraham.[1] 1. Al-Qur’an 21:68 speaks of Abraham being put into a fire. In this tradition it is said that the gecko blew on the fire to stir it up. (Bukhari and Muslim.)

وَعَن أم شريك: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَمَرَ بِقَتْلِ الْوَزَغِ وَقَالَ: «كَانَ يَنْفُخُ عَلَى إِبْرَاهِيم»
