Janab how is it to celebrate Mi'raj on the 27th night of Rajab and to keep fast on the day? Please reply without fail.
Undoubtedly, the event of Mi'raj is one of the major miracles of Nabi Sallallahu Alaihi Wa Sallam which is proved through Qur'an and Sunnath. However a fixed date of it is not known as certain, rather there remain quite a lot of different opinions in this context. Therefore, it is an Innovation and impermissible to celebrate the 27th of Rajab designating it to be Shab e Mi'raj and consider observing fasting on the day and it is necessary to refrain from it.
