Wazifa to grow tall

Q: I've heard a wazifa somewhere to grow tall. The wazifa is as follows: Take a glass half filled with water. Recite darood Ibrahim once. Recite first ayat of surah yusuf thrice and continue the ayat reciting ya allahu ya mureed. Again recite darood Ibrahim. Blow onto the water. Drink it in 3 breaths, keeping the image of your taller height in your mind. This has to be done twice a day after fajr and isha prayer. Is this wazifa right? Is there any other wazifa or du'aa for growing tall height?

Doubts regarding dirt on the carpet

Q: My query is as follows. Please could you assist. I found some dirt on my carpet and when I smelt it, it smelt like stool, I am not sure where it came from but my concern is that my family walked on the carpet with wet feet, however I am not certain if their feet did in fact touch the dirty parts of the carpet. They have subsequently touched their feet with their hands, does this make their hands as well as wet items they touched thereafter napaak? Also they have worn socks and shoes thereafter and possibly perspired in the shoes, are their shoes napaak as well?
