Shaikh Zayd al-Madkhali was asked:
“If I buy a car, should I place my hand on it and recite the supplication for buying a riding animal or is it sufficient just to make supplication?
“Yes, the supplication for [when buying] a riding animal is said for a vehicle” End translation.
Shaikh al-Albani rahimahullah said:
“Is this supplication [for when buying a riding animal] legislated for when buying a car? My answer is yes due to what is hoped from it of good and fearing its harm” End translation. [Aadab al-Zafaf pg. 93]
