You can talk to Allah (swt) in your own language on these nights

We must talk to Allah (swt) on these nights. We must ask Him to give us our needs. If you know the meaning of these supplications, you will see that the best and most eloquently worded requests that you can ask of God are in the supplications for the nights of Ramadan, the Supplication of Abu Hamza Thumali and the supplications for the Nights of Qadr. If you do not know the meaning of these prayers, you can talk to God in your own language.
