The trees and mountains greeting him (peace and blessings be upon him) with salam

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he said: We were with the Messenger of Allah (peace and blessings be upon him) in Makkah, and he (peace and blessings be upon him) went out to one of the outlying areas of Makkah. Every tree or mountain that came before him would call out: "As-salamu 'alayka ya Rasulallah" (Peace be upon you, O Messenger of Allah).
The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he said: I fell ill, and the Prophet (peace and blessings be upon him) came to me while I was saying (in supplication): 'Allahumma in kana ajali qad hadara fa-arihni, wa in kana muta'akhkhiran farfa'ni, wa in kana al-bala'u fa-sabbirni' (O Allah! If the time of my death has come, then grant me rest; if it is still delayed, then grant me cure (from the illness); and if this is a trial, then grant me patience). He (peace and blessings be upon him) said: "What did you say?" I repeated the same words, and the Messenger of Allah (peace and blessings be upon him) supplicated (for me): 'Allahumma ishfihi, Allahumma 'afihi' (O Allah, cure him; O Allah, grant him well-being). Then he (peace and blessings be upon him) said: "Get up." So I stood up, and that pain never returned to me after that.
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
