كتاب الطهارة وسننها
Read the English translation first, with the original Arabic directly underneath.
It was narrated that Jabir bin 'Abdullah said:
"The Messenger of Allah said: 'Beware of stopping to rest and praying in the middle of the road, for it is the refuge of snakes and carnivorous animals, and beware of relieving yourselves in the middle of the road, for this is an act that provokes curses.'"
إِيَّاكُمْ وَالتَّعْرِيسَ عَلَى جَوَادِّ الطَّرِيقِ وَالصَّلاَةَ عَلَيْهَا فَإِنَّهَا مَأْوَى الْحَيَّاتِ وَالسِّبَاعِ وَقَضَاءَ الْحَاجَةِ عَلَيْهَا فَإِنَّهَا مِنَ الْمَلاَعِنِ
