Hazrat Mohammad (s.a.w.a.) and his progeny (a.s.).
Imam Sayyidus Saajedeen – Imam Zainul Abedeen Ali
ibne Husain (a.s.) was asked about the reason about
salawaat at various places in supplications. He (a.s.) replied “It is very high and far from Allah that He
accepts one prayer of yours i.e. Salawaat and rejects
your other prayers”. Even if we recite salawaat for our
personal prayers then inshallah our prayers will be
accepted with the condition that, our prayers should be
legal (i.e. not prohibited) and it should not be harmful
for us.
