Kissing one’s thumbs when the name of the Prophet is mentioned is a bid’ah
Question

                do we kiss our thumbs when the prophet Mohammed’s (pbuh)name is said?
Praise be to Allah.
    As far as we know, there is no saheeh report from the Prophet  (peace 
    and blessings of Allaah be upon him) that when the muezzin says “Ashhadu 
    anna Muhammadan Rasool-Allaah” we should kiss our thumbs, so doing so is 
    a bid’ah (innovation). But it was proven that the Prophet  (peace and 
    blessings of Allaah be upon him) said, “Whoever innovates something in this 
    matter of ours that is not part of it will have it rejected.” And Allaah is 
    the Source of strength. May Allaah bless our Prophet Muhammad.
