The great contemporary scholar Shaykh Taqi Usmani (Allah have mercy on him) also mentions the non-offensiveness of this act in his “Discourses of Islamic Way of Life” thus he states:
“Upon listening to the Adhan in the Masjid, you heard the words “Ashhadu Anna Muhammad al-Rasul Allah” you suddenly felt a deep sense of love for the Messenger of Allah (Allah bless him & give him peace) and in this state of love and ecstasy you kissed your thumbs and placed them on your eyes. This action, in of itself, cannot be considered sinful or Bid’a. The reason being is that you did this out of love for the Messenger of Allah (Allah bless him & give him peace), and love and respect for the Messenger of Allah (Allah bless him & give him peace) is a praiseworthy act and a sign of faith….” (Islahi Khutbat (Urdu), 1/231)
The above statement from one of the renowned scholars of the Deobandi School clearly shows that the act of kissing one’s thumbs and placing them upon the eyes during Adhan is not, in of itself, an act of innovation. Those who categorically condemn this practice altogether should realize that it is not a baseless act that was invented by some Muslims in the Indian Subcontinent. It is something that is practiced in other parts of the Muslim and Arab world also, such as in Syria and Yemen. If one was to visit the famous city of Syria Halab (Aleppo), one would see many Arab Muslims including scholars kissing their thumbs and placing them on their eyes upon hearing the name of the Messenger of Allah (Allah bless him & give him peace) during the Adhan.
However, the other side of the coin is what we are discussing in this article, which is to over-emphasise something that may be merely considered a recommended act. Unfortunately, the other extremism found in some of our brothers is that they consider this act to be firmly established through the Sunnah like it is mentioned in a Hadith of Sahih al-Bukhari, hence they consider it to be a sign of being a true Muslim, and the one who does not kiss his thumbs is committing a sin. Thus, Shaykh Mufti Taqi Usmani (may Allah preserve him) further states:
“However, if an individual begins to tell the whole world that whenever during the Adhan you hear “Ashhadu Anna Muhammad al-Rasul Allah” you must all kiss your thumbs because it is Sunnah or Mustahab to do so, and whoever fails to kiss his thumbs does not truly love the Messenger of Allah (Allah bless him & give him peace), then this act, which was otherwise completely permissible, will become an act of reprehensible innovation. This is a minute difference between the two situations, in that if this lawful act is done with a right attitude, then it is not an innovation. However, if it is considered binding or thought to be an established Sunnah to the point that the one who wishes not to practice it is condemned, then it will become an innovation.” (Islahi Khutbat, 1/231)
