Abu 'Ubaid said:
I saw 'Ata b. Yazid al-Laithi praying in a standing posture. So I went to him passing in front of him; he, therefore, turned me away. He then said to me: Abu Sa'id al-Khudri reported the Messenger of Allah (ﷺ) as saying: If anyone of you can do that he should not let anyone pass between him and the qiblah, he should do it.
