As a result of the Defragmentation, The LDF and MDF has grown in its size.

Once completing the Defragmentation on the database, Is it correct practise, to Shrink them ?

OR

Once completing the Defragmentation on the database, Reindex the database and then Shrink.

This is needed since the MDF and LDF file sizes have grown as a result of Defragmentation.

Please Advise the best practise and many thanks to all of those participated.

Do NOT shrink the database after defragmenting it. You will only cause more fragmentation.

It is NOT a best practice to shrink a database, doesn't matter if you've reindexed or not.

Never shrink on a regular schedule. It should only ever be done manually and only if you know you don't need the space again (such as due to a large delete).

Do NOT shrink!
