I feel like sending Salam to all Mu'mins in my dua after prayer, otherwise every dua becomes too self-centred.
Is there any dua particularly for this purpose?
A good dua for mu'min slaves can be a part of Tashahhud.
Assalamu 'ala 'ibadillaahis salehin.
السّلام علی عباد اللّه الصلحین
Peace on the righteous slaves of Allah
