If a person is trying to recite the Quran properly but he cannot pronounce some makharij of some alphabets properly will his salah be valid although he is working on pronouncing it properly.
بسم الله الرحمن الرحيم
(Fatwa: 1128/940/H=09/1440)
If after full efforts he is unable to pronounce correctly then too his salah will be valid. In future too he should try his level best and do not do any negligence in this regard.
Allah knows Best!
