'Abdullah bin Harith bin Nawfal

It was narrated that 'Abdullah bin Harith bin Nawfal said:"I asked whether the Messenger of Allah prayed voluntary prayer when traveling, but I could not find anyone to tell me until Umm Hani' bint Abu Talib told me that he had come during the year of the Conquest (of Makkah). He ordered that a screen be held up, and that was done, and he took a bath; then he prayed eight Rak'ah (units) of voluntary prayer

It was narrated from ‘Abdullah bin Harith bin Nawfal that Ibn ‘Abbas commanded the Mu’adh-dhin to call the Adhan one Friday, which was a rainy day. He said:“Allahu Akbar, Allahu Akbar, Ashhadu an la ilaha illallah, Ashhadu anna Muhammadan Rasulullah (Allah is the Most Great, Allah is Most Great, I bear witness that none has the right to be worshipped but Allah, I bear witness that Muhammad is the Messenger of Allah).” Then he (Ibn ‘Abbas) said: “Proclaim to the people that they should pray in their houses.” The people said to him: “What is this that you have done?” He said: “One who is better than me did that. Are you telling me that I should bring the people out of their houses and make them come to me wading through the mud up to their knees?”
