From the stories of Al-Allaamah Rabee Bin Haadee Al-Madkhalee
Al-Allaamah Rabee Bin Haadee Al-Madkhalee (may Allaah preserve him) said:
One day I was coming from Bat-haan and entering into Madeenah; thus in front of me was a car and in it was (written) ”Yaa Allaah! Yaa Muhammad” with a red writing. I steered my car behind this car and its driver sped off, for he understood that I did realize (the shirk written in his car). He drove off fast and I drove fast behind him until we got close; then he stopped the car and came out. He said: ”Did you touch it (i.e. his car)?” I did not speak to him just yet, because he realized it (i.e. that his car was touched). I said: ”Yes, I did touch it.” This highlights (the fact) that he was under siege. Lay a siege against these superstitious grave worshippers in the land of Tawheed (i.e the land of true Islamic Monotheism).
