However, the big question to ask is…….
--------------------------------------
What did the Prophet (Sal Allaahu Alaihi Wassallam) do when the same day arrived the next year ?
Or the year after that ?
Or the year after that ?
Did he EVER celebrate the night of al-Israa wal Miraaj, or fast the next day ???
And what did he instruct the Sahaabah to do about his Night Journey ?
Did he tell them to celebrate that night as a special night for worshiping Allaah ?
Did he tell them to specifically fast the next day because it was ‘the day after the Journey’?
And what were the actions of the Sahaabah themselves ?
Did THEY do any of the above??

The answer to all of the above is a big resounding NO !
-------------------------------------------------------
Surely the Prophet (Sal Allaahu Alaihi Wassallam) did not omit or forget anything in the deen! Surely he did not hide anything from mankind!

The Prophet (Sal Allaahu Alaihi Wassallam) said, “There is nothing that brings you closer to Jannah except that I have informed you about it and there is nothing that brings you closer to the fire of Hell except that I have warned you against it.”
