It is reported about Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he used to come to a tree between Makkah and Madinah and rest beneath it, and he related that the Prophet (peace and blessings be upon him) had also done so.
Al-Bazzar recorded it, and its narrators have been declared trustworthy.
