Assalam ualaykum Is it true according to Holy Quran and authenticated Hadiths that reciting soorah Baqarah helps in solving the problems even bigger than Ohud Mountain?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

We have not come across any specific evidence which states that Soorah Al-Baqarah [Quran Chapter 2] helps in solving problems even if they were like the Mountain of Uhud.

However, it was reported in general that reciting it is a blessing as the Prophet said: ''Recite Soorah Al-Baqarah as reciting it is a blessing, and abandoning it is a cause of grief, and the magicians cannot confront it." [Muslim]

For more benefit on the virtue of Soorah Al-Baqarah, please refer to Fataawa 1447 and 19497.

Allaah Knows best.
