The issue of Kissing Thumbs and the Nail of the Index finger during Adhan and upon hearing the name of the Prophet (Sallaho Alaihe Wassallam)

The number of Sahaba (RA) exceeds thousands (and even hundred thousand according to some estimates) and since Adhan is called five (5) times a day, the name Muhammad (Sallaho Alaihe Wassallam) must have been uttered in front of them and in the blessed presence of Rasul-ullah (Sallaho Alaihe Wassallam) literally millions of times (in Adhan and outside of it) and if kissing the thumbs or the nail of the index finger was Sunnah then the books of Hadeeth would have recorded the actions of such lovers of the prophet (Sallaho Alaihe Wassallam).

Mawlid: An innovation By Shaykh (Mufti) Ismail Moosa (HA)

It will not be permissible to celebrate the mawlid even if a person beliefs that the Prophet is not present.
