Regarding Thirty Letters of Arabic Alpabets (Seeh Harfi): Hazrat Sultan Bahu Qaddas-Allah Sirru-hul Aziz has mentioned the Thirty-Letters of Alphabet in his many books as Naqsh and Daira (Circles). This Naqsh of Thirty-Letters (Seeh Harfi) is also present in Noor ul Huda Klaan book. Hazrat Faqeer Noor Muhammad Kulachvi Rahmatu-Allahe Ta-aala Alaihe has explained them at P161 in Haq Numa which is Urdu Translation of Noor ul Huda Klaan. Many other prominent personalities have also written a lot in this subject like Shaikh Akbar Muheyudin Ibne Arabi in Futuhat Makkiya Allama Abdul Rahman Inbe Khuldoon Al Maghrabi in Muqadima Inbe Khuldoon Shaikh Abul Ayaas Ibne Ahmed Bin Ali in Shamsul Arif and Hazrat Hasan Nizami Dehlvi in Asraar Ism-e-Azam.Hazrat Sultan Bahu Qaddas-Allah Sirru-hul Aziz has disclosed the philosophy and Secret of Inscribing these Letters in Visualization. By the Visualization of these Letters of Alphabet all those benefits and purposes are achieved by a person which are related with them and tied with them. In the Naqsh inside the Daira (Circle) of each of them is written the words of Visualization (Tasawwar) Tasarruf Kaleed (Key) and Haziraat. This means that when these Letters are Visualized it opens the way of Visualization its Tasarruf is achieved you get its Key and get its Haziraat. All languages all Divine Scriptures all sounds and voices are based upon these Thirty-Letters. Nothing is beyond their scope. [Explanation by Dr. K.B. Naseem Rh. P120 Aqal Baidaar]
