All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
It is not permissible to park cars in such streets that are intended for people to tread, if this harms them.
Parking cars in this manner is not of the characteristics of the believer, as stated by Shaykh Ibn 'Uthaymeen .
The jurists stated that a person bears the liability in the event of causing harm to people because of this act (parking the car in this manner).
Allah knows best.
