I have wiswaas where I keep doubting whether I said the اللهم بارك على محمد وعلى آلِ محمد... portion every single Salah, sometimes I start to repeat it but then I think no I should have ignored it, but then I think now that I have repeated must I do Sujud As-Sahw? This doubt keeps coming

Ustadh AbdulAziz al-Haqqan

Waswas therefore ignore it and in sha'a Allah u have said it.
