To offer As-Salat (the prayer) in the camel yards (the places where the camels are stationed)

Narrated Nafi:

"I saw Ibn 'Umar praying while taking his camel as a Sutra in front of him and he said, "I saw the Prophet doing the same."

حَدَّثَنَا صَدَقَةُ بْنُ الْفَضْلِ، قَالَ أَخْبَرَنَا سُلَيْمَانُ بْنُ حَيَّانَ، قَالَ حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ نَافِعٍ، قَالَ رَأَيْتُ ابْنَ عُمَرَ يُصَلِّي إِلَى بَعِيرِهِ وَقَالَ رَأَيْتُ النَّبِيَّ ﷺ يَفْعَلُهُ.
