In the tashahud after doing shahada of Prophet Muhammad (before Salwat) if I pause to think of my pronunciation and after a gap of pause I decide to repeat the recitation, do I just repeat that statement of Prophet shahada, or should I restart the tashahud recitation from start.The reason I’m asking is because if I repeat just the one sentence of prophet shahada, the sentence starts with “wa ashhadu anna muhammadan…” – the “wa” means “and” which implies an extension of previous sentences. Since I’ve made a pause, does this sentence in its own suffice?
