Re: Rulings about the 15th of Sha3baan
I am not Nauzubillah Allah(SWT) so I do not know for certainty if Allah(SWT) will reject ibadah because someone did it because of a weak or fake hadees. I hope Allah(SWT) out of Allah’s mercy will accept all ibadah if they are not done to show off others(ria kari) .
Remember one persons weak or fake hadees is true and carved in stone hadees for other. They are doing ibadah because they are sure that a hadees which makes you to do more ibadah cannot be weak or fabricated. Due to Islamic principle of “Innamal amaloo bin niyaat” Actions depend on intentions Allah(SWT) will accept these ibadah , Inshallah.
You should worry about your own ibadah and you should do your ibadah on the days , months and times you think are right , leave others alone to do their ibadah according to their own beliefs.
Allah(SWT) cannot be unjust to reject any ibadah. Allah(SWT) knows that people are worshiping Allah(SWT) not Month of Shaban or 15th day or night of shaban. People are reading Quran which Allah(SWT) sent are they reading different Quran ? Quran promises to reward its reading on anytime , any day or any month , it does not forbid you from reading Quran on any special night of special month.
People are praying nawafil which you can read on any day , any night , any month are they praying nawafil for nazubillah for some other deity other than Allah(SWT) ?
