Zayd bin Wahb (may Allah have mercy on him) says that Umar bin al-Khattab (may Allah be pleased with him) used to give us time to rest in Ramadan, that is, between two sets of tarawih he would give a break long enough for a person to go out of the mosque to the hill of Sal'. Perhaps he meant the one who led the tarawih by the order of Umar bin al-Khattab (may Allah be pleased with him).
