Why is there no Alif in the "بسم" of the Basmallah that precedes most chapters of the Qur'an whereas in Sura al-Haaqqa the verse 69:52 "فسبح باسم الربک العظیم" contains an Alif in "باسم"?
The writing of Quranic words is different from the usual Arabic alphabetical writing. Quranic writing is called Tawqeefiyyah ( توقيفية )which means that it is fixed and unchangeable as the Prophet Muhammad (SAWA) instructed Imam Ali (AS) when he wrote the Quranic text. There are many examples of Quranic words written is a different way from the Arabic Alphabetical words. No doubt, Quran is in Arabic, but the Quranic writing is special and it is called Tawqeefiyyah.
