Hazrat Abu Al-Ala bin Shikhir narrates from his father that he offered prayer with the Messenger of Allah (peace be upon him), and the Prophet (peace be upon him) spat out phlegm and rubbed it with his left shoe. Khalid has added in his narration that "and the Prophet (peace be upon him) was in a region with hard ground." Imam Abu Bakr (may Allah have mercy on him) says that Abu Al-Ala is Yazid bin Al-Shikhir and is the brother of Mutarrif. The narrators of the hadith have attributed him to his grandfather. Imam Abu Bakr (may Allah have mercy on him) says that this hadith was narrated by Hammad bin Salamah from Jariri, who said, «‏‏‏‏عن ابي العلاء عن مطرف عن ابيه» ‏‏‏‏
