15. Sahl has narrated from Ahmad ibn Muhammad ibn abu Nasr from Hammad ibn ‘Uthaman from ‘Amir ibn ‘Abd Allah who has said the following: “I heard abu ‘Abd Allah عليه السلام, say, ‘On the gravesite of Ibrahim, son of the Messenger of Allah, there was a palm tree that provided shadow and it would turn as the sun moved to provide shadow for the site but when it dried up, the gravesite became old and indistinguishable.’”
