"0 Messenger of Allah ﷺ, there are many (dangerous) pests and wild animals in Al-Madinah." He said: "Can you hear (the words) 'Come prayer, come to prosperity'?" He said "Yes." He said: "Then be quick to respond," and he did not grant him a dispensation. (Using translation from Nasāʾī 851)
أَنَّه قَالَ يَا رَسُولَ اللهِ إِنَّ الْمَدِينَةَ كَثِيرَةَ الْهَوَامِّ وَالسِّبَاعِ فَقَالَ «هَلْ تَسْمَعُ حَيَّ عَلَى الصَّلَاةِ حَيَّ عَلَى الْفَلَاحِ» قَالَ نَعَمْ قَالَ «فَحَيَّ هَلًا» وَلَمْ يُرَخَّصْ لَهُ
