Today's harf is "Zu'aad''.
Here's how the letter "zu'aad" is written by itself, and also in its initial, medial and final position:
Here's my attempt at writing "zu'aad" and the word which begins with it. The word I've picked is much used and abused on the sub-continent: "zaruur". Its meaning ranges from "sure!" to "definitely" and is dropped as regularly colloquially as the definite article is dropped while speaking English (in India, at least!).
"Zaruur" comparises of "zu'aad", "re", "vao" with a "pesh" and a "re", written, you will remember, from right to left, as seen at the bottom of my page.
The lafz "zaruur" reminded me of a lovely Wajida Tabassum ghazal:
Kuchh na kuchh to zaruur hona hai
saamna aaj unse hona hai
toDo phenko, rakkho, karo kuchh bhi
dil hamara hai, kya khilona hai
