Hadith 146:13
'Abd al-Razzaq narrated to us, he said: Ma'mar informed us, from al-Zuhri, from 'Abd Allah ibn 'Amir ibn Rabi'ah, from his father, who said: "I saw the Messenger of Allah, may Allah bless him and grant him peace, praying the voluntary prayers on the back of his riding beast in every direction."
حدثنا عبد الرزاق، قال: أخبرنا معمر، عن الزهري، عن عبد الله بن عامر بن ربيعة، عن أبيه، قال: " رأيت رسول الله صلى الله عليه وسلم يصلي على ظهر راحلته النوافل في كل جهة "
