Zayd bin Aslam زيد بن أسلم · The Book of Purification and its Sunnah

"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.'"

"A complaint was made to the Prophet about a man who sensed something (some doubt about his ablution) during prayer. He said: 'No (he does not have to perform ablution) unless he notices a smell or hears a sound.'"

"The Prophet was asked about doubts (concerning ablution) during prayer. He said: 'he should not leave until he hears a sound or detects an odor.'"

The Messenger of Allah wiped over his leather socks and his head cover (i.e., over the Imamah).
