When I recite Holy quran I have problem reciting generic Alif in the beginning of word so by generic Alif I mean Alif without kasrah fatha dhama etc nothing on top of the Alif so I was wondering if there is a formula on how to read the generic Alif …The below are just some example for holy quran some generic I can read it but some I do not know how to read it if you can please help me out

Surah 2:16. اشْتَرَوُا الضَّلَالَةَ

2:17. اسْتَوْقَدَ

2:20. يَكَادُ الْبَرْقُ

2:21. اعْبُدُوا

2:22 الثَّمَرَاتِ
