on the authority of abu zayd ibn akhtab (may allah be pleased with him), he said: "allah's messenger (peace be upon him) passed his hand on my face then invoked allah for me."

azrah said, that (abu zayd ibn akhtab) lived one hundred and twenty years, and had only few grey hairs.' narrated by al-tirmithi, considered as a “hasan” hadith by al-hakim and al-dhahabi agreed with him.

on the authority of jaber ibn samurah (may allah be pleased with him), he said: "when boys passed by the prophet (peace be upon him), he would pass his hands on one or both of their cheeks. when i passed by him, he passed his hand on one of my cheeks. my cheek which the prophet (peace be upon him) had passed his hand on, looked better than the other one." narrated by at-tabarani and its origin is in sahih muslim.

on the authority of abu dharr (may allah be pleased with him): "i attended a session for allah's messenger who then was holding a handful of gravel then the gravel said: 'subhan allah' i.e., all praised be to allah). abu bakr, omar, `uthman and `aly were among us. all those who were in the session heard the gravel's tasbih (saying:'subhan allah' i.e., all praise be to allah)" narrated by al-tabarani and the “isnad” (chain of narrations) of at-tabarani is “sahih” right with reliable narrators.

this is well-expressed by sheikh jamal addien abu zakariya yahya ibn yusuf as-sarsari who said in a poem:

while mountains praised allah responding to dawood (david),

and titanic iron became flexible,

hard rocks turned flexible, and gravel praised allah in his palm.

while springs of water gushed forth by moses' staff,

water gushed forth from muhammad's palm.
