salams bro/sis

one of the companions told the prophet "what do i do about thoughts that occur to me that the sky would drop if it was revealed to it", basically the prophet advised him to make isti'3atahh (say a'3uthu bilah)

and focus your attention on something else.. it happens to me too sometimes, i try dodge it by saying a'uthu bilahi minasahytanirajeem... or 'astaghfirullah' and focusing my attention on something else..

As long as they are thoughts that coem across without your will, Allah doesn't burden a soul beyond its capacity, as long as you don't dwell on them or happily accept them.

Take caer all the best!

ps: doing thikr whenever you're free helps alot too.. keep ur tongue soft with the thikr of Allah.
