Kissing the thumbs when hearing the name of the Prophet (peace be upon him),
especially when hearing Adhan (Call to Prayer); is it a part of Sunnah or is it a Bid`ah (innovation in religion)? Could you explain to us the Hadith which was related by the Companions of the Prophet (peace be upon him) that
Abu Bakr Al-Siddiq
(may Allah be pleased with him) used to kiss his thumbs at hearing the Adhan and at hearing the Prophet's name and considered it a good act. Is this Hadith Sahih (authentic) or not? Could you explain to us the ruling on kissing the thumbs at hearing the Adhan and at hearing the Prophet's name. May Allah reward you.
Kissing the thumbs at hearing the Prophet's name during Adhan, or otherwise is a Bid`ah which has no basis in Islam. It is authentically reported that the Prophet (peace be upon him) said:
Anyone who does an action which is not stated in this matter of ours (Islam) will have it rejected.
i.e. will be rejected from whomever performs it. We do not know any basis for what has been ascribed to
Abu Bakr Al-Siddiq (may Allah be pleased with him).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
