Ziyad bin 'Alaqa زياد بن علاقة · The Book on Salat (Prayer)

"I heard Allah's Messenger reciting for Fajr: And tall date palms in the first Rak'ah.

"Al-Mughirah bin Shu'bah les us in Salat. When he prayed two Rak'ah he stood without sitting. Those who were behind him said 'Subhan Allah' and he indicated to them that they should stand. He said the Taslim when he had finished his Salat and he performed two prostrations of As-Sahw, and said the Taslim. He said that Allah's Messenger did this."

They were with the Prophet (S) on a journey. They wound up in a narrow area when Salat became due. Then it began raining from the sky above them, and it was wet beneath them. So Allah's Messenger (S) called the Adhan while he was on his mount, and then the Iqamah, going forward on his mount. He let them in Salat by making gestures, making his prostrations lower than his bowing.
