As salaamu alaykum.
In many a Darul Uloom one sees that the hadith collection "Zaad ut Taalibeen" is used to teach Arabic. Specifically, the hadith contained therein are analyzed grammatically, i.e. I'rab or "Tarkeeb" of them is made. I am sure that doing so has proven effective at teaching Arabic or I'rab or else the practice wouldn't be so widespread. However, how valuable or effective do think this method is? Furthermore, at what stage of one's Arabic learning journey are its benefits best realized?
I once read a post of Mufti Yusuf Mullan's on forums.shariahprogram.ca where he commented that making I'rab of some of the longer sentences in Qasas book 3 was probably more beneficial for a student who completed books 1&2 rather than doing Tarkeeb of the hadiths contained in Zaad ut Taalibeen. Does anyone else agree?
Furthermore, to repeat a previous question, exactly when and at what stages of one's Arabic learning journey would making Takeeb of Zad ut Taalibeen be most beneficial? Further still, how can one maximize its benefit for this purpose?
If some of my more experienced and knowledgeable brothers and sisters could shed light on the above insha'allah, I would appreciate it.
