Is reading subhan Allah, Alhamdullilah, Allah u akbar,,, with the tasbi(chain of beads) an innovation? Is there any authentic Hadees regarding dis.. I know it’s better to read it on your fingers, but sometimes I just miss out the counts, so can I use tasbi as well..and reading with tasbi chain reward is equivalent to that of reading in fingers??
