One of the best books like Ja-al Haq I've ever read is Haq Par Kohn. I cannot believe it has not been translated into english yet! Written by Allama Muhammad Zafar Attari, it provides simple evidences for various topics from; The Quran, The Hadith, The Salaf, The 4 Imams, The Khalaf etc. with Arabic quotes that include Tashkeel Here is just a snapshot of the cover, contents and content: Online PDF is finally available in highquality as well (~70MB): http://marfat.com/DownloadBooks/Haq Pr Kon/WQ.pdf
I found one book by Allama Syed Shah Turab ul Haq Qadri Sahab, called "Rasool e Khuda Ki Namaaz". A simple, but very effective book dealing with issues such as: 1. Rafa'a Yadain. (Raising of Hands) 2. Mode of Prayer for Women 3. The history of ghair muqallid (la mazhab) sect 4. Taqleed (following a mazhab) 5. Raising hands up to ear-lobes to start Prayer. 6. Method of folding hands in Prayer. 7. Qir'at behind an Imam 8. Saying "Aameen" softly 9. Witr Salaah is 3 Raka'ah 10. Taraweeh Salaah is 20 Raka'ah 11. The Funeral Prayer 12. The Sahabah used to offer prayer, wearing caps & turbans
Aqdas, Shaykh Zayn al Sumayt wrote a very nice book that is suitable for people of ages. You should look at that.
Also if you go into the Permissible & Forbidden folder there is another folder within it named Tawassul & Istighātha this should also be helpful to you In-Shaa-Allah
If you click the Aqeeda folder in this library there is a another folder within that called Proper Sunni Belifs, it contains a book called: Traditional Scholarship & Modern Misunderstandings. I believe this may be a good brief work that should come in handy In-shaa-Allah The Voice Of Truth PDF Library Books By: Sheikh Abdul Qadir al-Gilani, Imam al Ghazali, Hazrat Data Ganj Bakhsh Ali Hajveri, Imam Ahmad Ridha Khan, Maulana Muammad Ilyas Attar Qadiri.
